Unformatted text preview: Theoretical ATP Yield of Aerobic Respiration Glucose is entirely consumed. One of the carbons in pyruvate is lost as CO2 in the conversion to acetyl CoA. Two other carbons are lost during the oxidations of the Krebs cycle. 2 molecules of ATP Glycolysis Two more ATP molecules have been made Krebs cycle. Twelve electron carriers have been reduced (10 NADH + and two FADH2) and H has built up
Actual Yield: 30 molecules of ATP 1. "Leaky" inner mitochondrial membrane 2. H+ gradient - uptake of pyruvate 3. NADH - energy to other molecules 4 Substrate Phosphorylation 25 - NADH (2.5 / 10 molecules) 3 FADH2 (1.5/2 molecules) 32 - 2 - (transport of glycolytic NADH) 30 7.3x30/686 = 32% efficiency ...
