A glucose (six carbons) molecule enters glycolysis and produces two three carbon molecules (pyruvate). Each pyruvate is broken down into a two carbon acetyl-CoA molecule that enters the citric acid cycle. Each acetyl-CoA molecule produces three and one in the citric acid cycle. read more

The reactants of the Krebs cycle include acetyl CoA, NAD, FAD, ADP and HPO4-2. The net equation for the cycle is acetyl coA + 3 NAD + ADP + FAD + HPO4-2 €”> CoA + 2CO2 + 3 NADH+ + FADH+ + ATP. read more
