Yeah - let's eat a snack.
Uh huh.
In high school I confused by oxidation of food.
Seemed to complex. Glycoly- had me confused.
But it's a simple concept, so now I'm in the mood for
...learning how I'm burning glucose as a food source.
I want to live good so my cells take energy
from the bonds in the sugar - put 'em into ATP.
Takes ten enzymes. Takes ten steps.
Wind up with two pyruvates. Yeah - still got energy left.
So mitochondria can take 'em to burn.
it down to acetyl-CoA so Kreb's gonna turn.
So the energy you get from eating them blueberries is ferried to where high energy electrons are carried.
Hate it or love it glycolysis gon' chop
glucose down to two 3C blocks (pyruvates).
Go ahead study me. I make ATP. And I'ma be on your test so you should get to know me.
And if you got enough oxygen in stock, Kreb's gonna cycle, homie, until your heart stops.
Go ahead study me. I (Kreb's Cycle) help make ATP, by making NADH, so you should get to know me.
NADH Dehydro! Inner membrane of the mitochon(dria) - using NADH from Kreb's to pump protons.
...thanks to electrons, which we transporting
So important that we gotta switch it to the next song.
So many ways to pump protons.
Ha - yeah. Choose one.
(Choose one!)
Aye.
Now let 'em flow.
Yeah.
And watch your ATP supply grow.
Electron to the next one.
Hold up - freeze.
Somebody synthesize some ATPs!
Oxy- phos- is pretty complex. 
Students say, "How come?"
Wasn't so many steps - inefficient outcome.
If the energy from the food that you eat was burned in one big step, then you'd lose more as heat.
So when those e minuses (electrons) move down the chain, they make protons move across the membrane.
And when the pro(ton) flow gets the synthase a-rumbling to make ATP - chemiosmotic coupling.
But as electrons get passed along, see, to help do their work they lose a little moxy.
So by the end, you gon' need an oxy
to remove the e- and keep it rolling like Yahtzee.
Kreb's making CO2. Oxygen's oxidating.
Why do you think they call it cellular respiration?
Burning our food to make ATP stacks, son.
Oxygen present? Electron to the next one.
Lollipops and tangerines.
Somebody synthesize some ATPs!
So all you kids thinking - "what's the point of all these?"
Crazy steps? What a mess making ATPs?
Why you gotta do from glu- to pyru?
From Co-As to synthase?"
Shoot, why do you think we need to breathe?
Well, adenosine triphosphate's (ATP) beauty
It ain't hard to tell, helps the cell do its duty.
Even Judy could judge that it's crucial to me.
To pump sodium and keep myosin moving.
Which is to say that it's fuel for your brain or your muscles in a tussle, insane.
So when you think, jerk, run, ball, take a test, or drop new flows
Remember how you made ATP out of glucose.
Hate it or love it glycolysis gon' chop.
glucose down in two three-C blocks (pyruvates).
Go ahead study me. I make ATP.
And if you eat a burrito then you could get to know me.
And if you got enough oxygen in stock, mitochondria will do oxidative phosphorylation.
Go ahead study me (oxidative phosphorylation). I make ATP.  I make a helluva lot so you should get to know me.
