Question

Which of the following identifies net production when 1 mol of fructose-1,6-bisphosphate is converted to 2 mol of lactate? Assume that re-oxidation of NADH via the electron transport chain yields the equivalent of 3 ATP, and that re-oxidation of FADH2 yields 2 ATP.

a. 2 mol of ATP

b. 4 mol of ATP

c. 2 mol of ATP + 2 mol of NADH

d. 4 mol of ATP + 2 mol of NADH

Explanation / Answer

in glycolysis conversion of fructose 1-6 biphosphate to 2 molecules of pyruvate yeilds 2 NADH and 4ATP molecules. pyruvate---------------------------------------------->lactate NADH----------------->NAD Above reaction shows loss of NADH in coversion of pyruvate to lactate Ans. b)hence conversion of fructose 1-6 biphosphate to 2 molecules of lactate yeilds net production 4ATP molecules.
