Cell Respiration Basics

oxidation

gain of oxygen; loss of hydrogen; loss of electrons

reduction

loss of oxygen; gain of hydrogen; gain of electrons

dehydrogenases

enzymes that remove/transfer hydrogens

oxidases

enzymes that remove/transfer oxygens

coenzyme from niacin

NAD

coenzyme from riboflavin

FAD

glycolysis location

cytosol

transitional stage & Krebs Cycle location

mitochondrial matrix

oxidative phosphorylation location

mitochondrial cristae

glycolysis purpose

breakdown of glucose

transitional stage purpose

breakdown of pyruvate

Krebs Cycle purpose

breakdown of Acetyl-CoA (complete breakdown of all carbons)

oxidative phosphorylation purpose

'cash in' on coenzymes; produce most ATP

NADH+H exchange rate

2.5 ATP on average

FADH2 exchange rate

1.5 ATP on average
