Question

The reaction cycle that uses acetyl CoA to generate electron carrier molecules needed in the electron-transport chain is important for powering the cell. Which of the names below is not one of those commonly used to describe this reaction cycle? Select one: a. tricarboxylic acid cycle b. Krebs cycle c. oxaloacetic acid cycle d. citric acid cycle

Answer 1

The acetyl CoA-generated electron carrier molecules are essential for the electron transport chain, but the term "oxaloacetic acid cycle" is not commonly used to describe this specific cycle. Therefore, the correct option is C.

Step-by-step explanation:

There are several names for the cycle of reactions that use acetyl CoA to produce electron carrier molecules that are necessary for the electron transport chain. But "oxaloacetic acid cycle" isn't the usual term among the ones used to characterise this particular cycle.

The metabolic pathway is referred to by the accurate words a. tricarboxylic acid cycle, b. Krebs cycle, and d. citric acid cycle. Acetyl CoA enters the cycle in this way, mixing with oxaloacetic acid to make citric acid. This sets off a chain of events that eventually result in the production of electron carriers, like NADH and FADH2.

For this reason, this metabolic pathway is not commonly referred to as the oxaloacetic acid cycle.

Therefore, the correct option is C.
