When we say that the efficiency of glycolysis is about 33% we mean that
A) 2 ATP are produced and 6 ATP are involved in the overall process
B) 2 ATP are produced in the oxidation of glucose, which contains six carbon atoms
C) the energy used to phosphorylate 2 ATP is 33% of the energy released in the process
D) all of these

Question

Quizplus · Accepted Answer

The efficiency of glycolysis refers to the proportion of energy captured in the form of ATP relative to the total energy released during the breakdown of glucose. When we say the efficiency is about 33%, it means that one-third of the energy released is used to synthesize ATP, as described in option C. Options A and B do not accurately describe the basis for calculating efficiency in terms of energy capture versus energy release.
