Il y a 3,5 milliards d'années, apparaissait la première forme de vie : la cellule, capable de s'autorépliquer grâce à l'ADN. Dans le corps humain, une cellule est à la base de tout. C'est une véritable usine, avec ses fabriques de production, de gestion d'énergie, ses réserves, son centre de décision.

00:00Life, life, life, life, life, life, life
00:06And here is life, beautiful life, eager to blossom.
00:13The world invites us to new dawns.
00:19He gives us tears that sing
00:23And the sun that dazzles us
00:27The crisp air entices us
00:30It fills us with joy and life
00:34Life, life, life, life, life, life, life.
00:53About ten billion years ago, the universe.
01:23Nearly 5 billion years ago, the Earth.
02:23It took one and a half billion years, 15 million centuries,
02:26so that this unique cell from which we all come can be formed.
03:02The person we will become still retains many vestiges of their very rapid evolution.
03:13For example, the liquid in which its cells are bathed is virtually identical to the seawater from which it comes.
03:25Or, her fingers expel fish.
03:34His coccyx is a vestige of the tail of the wise.
03:45His brain has three layers.
03:47The first of these, the articortex, comes from reptiles.
03:51The second, the paleocortex, of mammals.
03:56As for the third, the most important, the neocortex,
03:59It formed very quickly over the last 500,000 years.
04:03Yes, but of course, you already know all that.
04:06So, if you don't mind, let's go back.
04:09Okay, tell me, where are you going like that? Stop, I said, go back.
04:16A little faster, please, thank you.
04:30Okay, well, we'll leave again tomorrow.
04:34Here it is then, this primordial soup, the source of all life.
04:53Subtitling by Radio-Canada
05:16Hello, I am Enzyme, the cell's good genie.
05:22There ?
05:23A gene.
05:26So.
05:28Genes.
05:29And there you have it.
05:31Wait.
05:33Genes that will become chromosomes.
05:35Ah, well, oh dear, this isn't very solid.
05:39Ah, there it is.
05:40I have an idea.
05:41Ah, ah.
05:45Let's see, what does that give us?
05:56That's it.
05:58Hey, that's not bad at all.
05:59Eh, eh, eh, eh, eh, eh, eh, eh, eh, eh, eh, eh.
06:02Ooh, ooh, ooh, ooh.
06:03Oh, well, oh, well, oh, well, no, no, that's not true.
06:11Yes, it holds.
06:14Yes.
06:15Mm-hm.
06:21Genes that became chromosomes.
06:31This will make a presentable cell nucleus.
06:44Mitochondria, probably ancient bacteria, enclosed within the body of the developing cell.
07:03A cell is born, but it will need to multiply in order for life to emerge.
07:0960 trillion cells in a human body.
07:11Because everything, in living nature as in the body, everything is just a cell.
07:15The skin and bones, the nerves and muscles, the heart and the brain.
07:18And each of them, a living and autonomous organism, breathes, produces energy, nourishes its substance, reproduces.
07:25Its size, 1 hundredth of a millimeter.
07:28For it to be visible to the naked eye, the human body would have to be 500 meters away.
07:33And even then, it would only be the size of a pinhead.
07:54Who wants salt? Who needs salt?
07:57And minerals, here are some minerals.
07:59This way for carbohydrates, ask for carbohydrates.
08:02Come closer, come closer.
08:03Who wants some good fat?
08:04Who wants some?
08:11Let's go, I'll take you to the heart of the cell.
08:28Hi.
08:45Subtitling by Radio-Canada
08:59Oh no, we don't want the dust.
09:09Our cell is tired.
09:10It's true.
09:13Yes, he's right.
09:14We're exhausted, we can't take it anymore.
09:17We urgently need sugar.
09:19And fats, water, and proteins.
09:22And you heard, I think, right, that's clear?
09:28Yes.
09:50What did they teach you about traffic?
09:53Instead of being useful, he only thinks about having fun.
09:56But that is to say, he...
09:57He can still choose his cell, though.
10:00Come on, come on, move along.
10:05No respect for the workers.
10:07Ah, those polymorphic white blood cells, what do they think they are?
10:09Hold.
10:10These are friends.
10:12So, nothing to report, Lieutenant?
10:14Nothing.
10:17Nothing, Captain.
10:20Look, these are the red blood cells that bring us oxygen.
10:25Oh well, we certainly need it.
10:29They prefer that to getting rid of our carbon dioxide.
10:36Come closer!
10:37Come on, come on!
10:41Hey, my!
10:42Wait, I have an idea.
10:44Shh!
10:49But, but, but what is he doing?
10:51Hey Emo, maybe we could try to find out how a cell is made.
10:55What do you mean, Globine?
10:56There's no window and we're way too big to fit in.
10:59Oh, but we red blood cells are cells too.
11:02Us? Cells?
11:03Is that true, Mr. Jesus?
11:05Yes, except that we've lost our core
11:07and we cannot reproduce like other cells.
11:12Another shipment of carbon dioxide.
11:13There you go.
11:15Hey, hey, hey.
11:18Ha, ha, ha!
11:20Ah!
11:22Oh, we're going to go and visit the cell.
11:28Wow!
11:30Yeah !
11:31Yeah !
11:41Personally, I don't like carbon dioxide.
11:51Here we are, ladies and gentlemen, inside the membrane that protects our cell.
11:55As you can see, it is mainly composed of protein, fat, and sugar.
12:00Wow!
12:41MFP subtitles.
12:46Wait, and there you go.
12:48But what on earth is going on? What is this?
12:50Ribosomes are our protein assembly lines, and we have thousands and thousands of them.
12:58Mitochondria, our power plants.
13:00To provide it for us, they burn food that is brought to us.
13:04And besides, all the body's respiration takes place here.
13:13The centriole, the control station of the unit or division of the cell.
13:29This ribbon is messenger RNA.
13:31Look, he's going to carry the orders from command to our assembly lines.
13:35And the command center, precisely, is located there.
13:45Also admire the Golgi, our supply depots.
13:47And you know, we also manufacture for export.
13:56This is our goal. One of our lysosomes.
13:59This is where your transformation will take place.
14:02A new life awaits you.
14:04Oh, how pretty, how cute they are.
14:07That's true, that's true.
14:08Soon, you will become like them.
14:11Ah, help yourself.
14:12Hey, Sunday driver!
14:13You can't pay attention.
14:15Your idiot!
14:16That's true, that's true.
14:26Ah, I'm here.
14:31Ah, I'm here.
14:33Ah, I'm here.
14:43Ah, I'm here.
15:00It looks like there's a traffic jam.
15:06But what happens with deliveries, then?
15:08But answer me, my blood!
15:10There's nothing we can do, boss. We've done everything we could, believe me.
15:13Why don't you speed up the releases, finally?
15:14You can see that we are congested.
15:16The assembly lines are overloaded, boss. They're asking us to slow down deliveries.
15:21This cannot continue. Send all the surplus to Greece.
15:25Come on, get rid of it, let's get rid of it.
15:29Please put me through to the master right away.
15:44But I need the master urgently.
15:47The master is very busy.
15:54He's the teacher I need.
16:00He's the teacher I need.
16:04But what is it?
16:08Ah, good, there we go.
16:11What is it? I'm listening.
16:14Master, he says they are overwhelmed with food.
16:17They can only store Greek goods.
16:20Action must be taken.
16:22And in the other factories?
16:24But the situation is the same everywhere, master.
16:34Okay, we'll do what's necessary.
16:36Tell me, chief warden, are you asleep or what?
16:39Are you letting everyone in?
16:40So you don't know that our factories are overwhelmed?
16:42Of course he doesn't know.
16:44It is up to me to know.
16:45I'm the boss, after all.
16:47Okay, listen.
16:48From now on, you are blocking imports.
16:51Nothing else is getting in, do you hear?
16:54Send me a neuron messenger.
16:58Transmit that to the brain.
17:00If they still want to make bacon up there, that's their business.
17:03After all, this responsibility falls on them.
17:05But they shouldn't come complaining.
17:07after not having been warned.
17:14Nothing more for today.
17:16Sorry, nothing more.
17:22Please.
17:23They need me inside, you know.
17:28Psst! The coast is clear.
17:35No !
17:48Captain, look over there.
17:52Viruses enter a cell.
17:56I am requesting sector 4000.
17:57Put Lieutenant Petit Gros on the phone.
18:01Yes, Captain, we've just spotted them.
18:03But it'll be fine, no problem.
18:08Come on !
18:08One, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one,
18:18one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one,
18:24one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one,
18:24one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one,
18:24one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one, one,
18:25one, one, one, one, one, one, one, one, one, one, one
18:34Ouch!
18:47Ahead !
19:41Ah! Let's see, let's see!
19:43How does all of this work today?
19:47SO...
19:50We need a little sugar, okay?
19:52And oxygen, of course?
19:55And water, amino acids, yes, but above all, proteins.
19:58Proteins make up half of our structure.
20:01Well, how is it that there's more and more fat? That's weird.
20:04Ah, a pinch of salt. Okay, but that's all.
20:06All that remains is to place the order with the chief guardian of the membrane.
20:09while recommending that he strictly adhere to...
20:12Sector 4000, to all cells in sector 4000,
20:14Schedule the production of expedited collagen; as soon as it's ready, it's finished.
20:18Oh !
20:20Hey, headquarters, can't this order wait a little longer?
20:23I'd like to satisfy my own needs first, eh?
20:28Order from the general organism, the skin has just been injured, so do not argue.
20:31You know that export orders take priority.
20:34Okay, okay, okay, you heard, I suppose, we're cancelling everything and starting over.
20:37Chromosome room, a very urgent collagen order.
20:41Send the messengers to RN with the manufacturing plans to the assembly center, understood?
20:46So, let's get to it!
20:52Hey! What?
20:54Oh, well, what do you know?
20:55Hey you!
20:55And you, over there, at work, eh!
20:57Hey, let's jump!
20:59And you, over there at work, go, go, go, go, go!
21:43But what's going on, huh? What's going on, huh?
21:45At least that brought him here, wait!
21:47No, but, uh...
21:49But stop! Finally!
21:50Stop it immediately, you idiot!
22:00No, but seriously, that's not right!
22:01I said to send the messenger and the emissary and forward you the original, the DNA, the bullet of
22:05our genetic heritage!
22:07Without him, how would we reproduce?
22:09Good one, idiot, well done, did you hear that?
22:11I would like someone to explain to me how you could have done such a thing, finally!
22:16We are all perishable, but this capital is our relay baton for eternity!
22:20Go quickly and make me a duplicate!
22:23A messenger, not entirely incompetent!
22:40Let's go!
22:46Let's go!
22:47Success!
22:48Huh?
23:05And all of this happens in one of our cells, one of our sixty trillion cells.
23:12The order is ready, deliver!
23:15The cell, its size one hundredth of a millimeter.
23:20Every day, five hundred billion of them disappear to be replaced.
23:25Fifty million every second.
23:32Life, life, life, life.
23:35The soul and life listening to each other in serenity.
23:39Let's take up the challenge of making my joy busy.
23:45Life, life, life, life, life, life, that's life
