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