Cellular Respiration 1. Glycolysis Glucose Cellular Respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. 2 ATP 2 ADP 2 Triose Phosphate 4 ADP 4 ATP 2 NAD+ 2 NADH Glycolysis is the process In which one molecule of glucose is broken in half, producing two molecules of pyruvic acid, a 3-Carbon Compound Acetyl-CoA H+ FAD H+ NAD+ 4- Carbon Compound 2. Krebs Cycle e- 2 NADH 2 NAD+ ATP 4 H+ + O 2 2 H2O The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.

Electron carriers go to ETC (NADH and FADH). The ETC is also located in the Mitochondria and produces 32 ATP 36 ATP Cellular Respiration Cellular Respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. _______ _________ ____________ ______________ Krebs Cycle Total number of ATP molecules formed during cellular respiration NOTES:
