Question

how many atp are produced in glycolysis and krebs cycle

Answer 1

In Glycolysis after the step-wise disintegration of Glucose the final product is obtained in the form of Pyruvic Acid(2 moles)The 2 moles of Pyruvic Acidcannot enter the matrix of mitochondria hence converts into 2 moles of Acetyl CoA.Then starts TCA or The Kreb’s Cycle



The Kreb’s Cycle gives 3 moles of NADH, 1 mole of FADH and 1 mole of ATP per cycle of substrate i.e per 1 mole of Acetyl CoA. However if the examiner is shanna(cunning), he/she would ask the net ATP i.e after ETS which would make the answer to 12 ATP(9+2+1) respectively.
