Cellular Respiration Song

Science Songs

A process in bacteria, animals, and plants
In both the autotrophs and the heterotrophic
Cells use oxygen to turn your food into ATP

Your cells need energy to move and do things
So they use the food you eat to make ATP
The chemical that cells use for energy
Respiration that’s aerobic using oxygen that you breath

Four stages, that we’ll introduce then discuss in depth
First stage, cells break down glucose through glycolysis
Next pyruvate oxidation, then Citric Acid Cycle
Then it ends with oxidative phosphorylation

In your body
Cells turn food to energy
Glucose from the food you eat
Oxygen you breathe in
ATP energy

Release
Carbon dioxide when you breathe
Creates water when complete
Three products total with
ATP energy

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP)

First step, glycolysis in the cytoplasm
Glucose, a sugar that’s made of six carbons
Convert to two molecules of pyruvate
ATP is made, NAD plus converted to NADH

Each pyruvate in the mitochondrial matrix
Into a molecule of two carbons, converted
Joins an enzyme to make Acetyl CoA
Then releases CO2 and NADH is made

Citric acid cycle, Acetyl CoA that we just made
Combines with a four carbon molecule, creates
A regenerated four carbon molecule
and causes a release of a CO2
what’d we produce, a new:

ATP, FADH2 and NADH
Alright, now what do those do?

NADH and FADH2 that were made
Put electrons in the electron transport chain
Turned back to empty forms NAD+ and FAD
And now the protons are pumped out
Using energy released

(how about that last stage, what it do?)

Protons pumped back into the matrix in this last stage
A process through an enzyme called ATP Synthase
The oxygen takes electrons and protons
And then forms into H2O, a water molecule

In your body
Cells turn food to energy
Glucose from the food you eat
Oxygen you breathe in
ATP energy

Release
Carbon dioxide when you breathe
Creates water when complete
Three products total with
ATP energy

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP)
