The overall reaction in glycolysis can be summarized as

QUICK ANSWER…

B

DETAILS…  

Glycolysis involves a set of reactions that results in the breaking down of glucose into pyruvic acid hydrogen ion and ATP.

Now for the right answer to the above question:

  1. Option A is incorrect; this is because one molecule of glucose finally gives a net two ATP
  2. Option B is correct; in glycolysis, 1 molecule of glucose summarily yields 2 molecules of pyruvic acid, 4 molecules of hydrogen ion and 2ATP.
  3. The final product of glycolysis does not yield ADP. C is incorrect
  4. Actually, D is incorrect too; because the final product of glycolysis does not yield ADP.

KEY-POINTS…

You may please note that

  • This is the correct answer and balanced version of this question as many answers bandied about seem to be wrong.
  • The main equation actually starts with 2ATP to yield 4ATP, observe that the net gain of ATP is two.
  • Also, two pyruvic acid and not one pyruvic acid is yielded.
