How does cellular respiration work?
Carbohydrate, fat, and protein are broken down into glucose, fatty acids, and amino acids.
Glucose, fatty acids, and amino acids, along with O2 form Acetyl-CoA.
Acetyl-CoA is broken down in the mitochondria of a cell via the citric acid cycle to produce CO2 and some electrons.
Electrons are moved to the electron transport chain which allows for the creation of ATP.
ATP is then broken down into ADP + P + energy.
