Answer 1

QUESTION 1

In this context, the 6 carbon molecule of glucose will be converted into 2 molecules of pyruvate which are going to be oxidized. After that, acetyl is produced and taken to the citric acid cycle in order to produce NADH and FADH2. These two products will be oxidized in the oxidative phosphorylation process. So, the correct answer is B.
