Chapter 6, Problem 3.2SC
If four actual molecules of ATP are produced for each glucose molecule going through glycolysis, why do we say glycolysis yields only two ATPs?

Students have asked these similar questions
Glycolysis of one molecule of glucose produces 8 ATP molecules. How many ATP molecules are produced from glycolysis of 10 glucose molecules?
Of the 36 molecules of ATP produced by the complete metabolism of glucose, how many are produced directly in glycolysis alone, that is, before the common pathway?
During glycolysis (under
anaerobic conditions), for each
glucose molecule broken down,
how many ATP molecules are
used and how many are made in
total? A diagram summarizing the
different reactions of glycolysis is
given below.
