Aerobic Respiration Summary Zach Nebeker

Overview Includes:  Glycolysis  Pyruvate Oxidation  Krebb’s Cycle  Electron Transport Chain

Glycolysis Breaks down glucose to 2 pyruvate Occurs in Cytoplasm Net gain of 2 ATP and 2 NADH

Pyruvate Oxidation Occurs in the Mitochondria Produces:  1 CO2  1 NADH  1 Acetyl-CoA

Krebb’s Cycle

Krebb’s Cycle products 2 molecules of CO2 3 NADH reduced to NAD+ 1 FAD reduced to FADH2 1 ATP

Electron Transport Chain/Chemiosmosis Gradient of H+ used to power ATP Sythnase Produces ATP per glucose used
