Refer to the Table Showing an Accounting of ATP Yield

question 188

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.
