Homework Answers
Carbon atoms of the acetyl CoA are oxidized to CO2, these CO2 are released in step 3 and step 4 when Isocitrate is converted to alpha-ketoglutarate and when alpha-ketoglutarate is converted to succinyl CoA, both these steps requires NAD+, for citric acid cycle to start oxaloacetate is required so the answers are Oxaloacetate, NAD+

Assume a cell has just completed glycolysis and the resulting
pyruvate has a c-14 radio label on carbon -1. Highlight the carbon
on the attached pages as it passes through the PDH complex and the
TCA cycle until it is lost as CO2. If only a portion of the carbons
are lost stop highlighting when the CO2 first starts to come off.
