CELLULAR RESPIRATION▸Makes ATP from sugars and other carbon-
based molecules
▸Aerobic process - requires oxygen
▸Occurs in the mitochondria

3 STAGES IN CELLULAR RESPIRATION▸Glycolysis (outside mitochondria)
▸Makes a few ATP and NADH
▸Citric Acid Cycle (aka Krebs cycle)
▸Makes NADH, FADH2, and a few ATP
▸ Electron Transport Chain
▸Makes most of the ATP
![Page 9: day25-27 cellular respiration](https://reader034.vdocument.in/reader034/viewer/2022051114/62773d672283e35833443606/html5/thumbnails/9.jpg)
PAGE 39
GLYCOLYSIS▸Goal 1: split glucose into two pyruvate (pyruvic acid)
molecules. Needs 2 ATP
▸Makes 4 ATP
▸ 2 ATP TOTAL made
▸Goal 2: make NADH (carries e-)

CITRIC ACID CYCLE (AKA KREBS CYCLE)▸Goal: use pyruvate to make NADH and
FADH2

ELECTRON TRANSPORT CHAIN▸Goal: use NADH and FADH2 to make as
much ATP as possible
▸Needs O2
