At the end of the Krebs cycle glucose has been fully oxidize

At the end of the Kreb’s cycle, glucose has been fully oxidized to CO2. What molecules now contain the energy that glucose had?

Solution

The energy containing group after the complete oxidation of glucose are as following

10 NADH, 2FADH_2, 4ATP so total yield of ATP from the complete oxidation of glucose (vis glycolysis, pyruvate dehydrogenase complex reaction,TCA and oxidative phosphorylation)= 32 or 30. this is calculated as 2.5 ATP from NADH and 1.5 ATP per FADH_2.
