The production of ATP in glycolysis and the citric acid cycle occurs through
A) the removal of electrons and hydrogen from glucose.
B) the removal of a phosphate group from a substrate that is then added to ADP.
C) the capture of solar energy that donates electrons.
D) the breakdown of glucose to pyruvate.

Question

Quizplus · Accepted Answer

ATP production in glycolysis and the citric acid cycle occurs through substrate-level phosphorylation, in which a phosphate group is removed from a substrate and added to ADP to produce ATP. This process does not involve the removal of electrons or hydrogen from glucose, the capture of solar energy, or the breakdown of glucose to pyruvate.
