When considering all 10 steps in glycoside , 4 ATP molecules are generated from 4 ADP molecules. overall however only 2 net molecules of ATP are generated in glycolysis. How can this apparent discrepancy be reconciled

• 2 molecules of NADH are also made, and NADH can be considered equivalent to ATP

• 2 molecules of NAD+ are also made, and NAD+ can be considered equivalent to ATP

• 2 molecules of ATP are also lost(converted to ADP) during serval of the 10 steps of glycolysis

• Glucose which is a 6-carbon molecule is converted into two 3- carbon molecules (in step 4 of glyociss) so you must multiply the output of ATP by 2- fold (that is 2x2) to compensate

• When pyruvate is converted to acetylCoA by pyruvate dehydrogenase, 2 more molecules of ATP are formed , which are also counted in the amount of ATP generated by glycolysis

In step 5 of glycoside, one 3-carbon molecule is converted into another DHAP (dihydroxyacone phosphate) is converted into G3P (glyceraldehye-3 phosphate) why is this step essential

• Because DHAP can proceed to stop 6 while G3P cannot

• Because G3P can proceed to stop 6 while DHAP cannot

• Because a cleavage must occur between C2 and C3 in a subsequent stop of glycolysis which can only occur when -C=O is on C1 and not on C2
