Refer to the Table Showing an Accounting of ATP Yield

Multiple Choice

Refer to the table showing an accounting of ATP yield from different metabolic processes in a mouse cell.Yield is defined as the net number of molecules of ATP formed for every glucose molecule oxidized. Which statement explains why the two sets of values differ?

A) Some ATP is used in the beginning steps of glycolysis.
B) Glycolysis is a less efficient process than either pyruvate oxidation or the citric acid cycle.
C) Pyruvate oxidation and the citric acid cycle can only proceed when oxygen is present, whereas glycolysis is not dependent on oxygen.
D) NADH produced via glycolysis must be shuttled across the mitochondrial membrane through a process that converts each NADH to FADH₂.
E) Because glycolysis is the first step in the overall oxidation of glucose, there is more opportunity for ATP to hydrolyze spontaneously in the cell before it can be used.
