Is the Kreb's Cycle useful in the absence of terminal electron acceptors?
Homework Answers
In general oxygen is terminal electron acceptor in kreb cycle. citric acid cycle can not occur if there is not NAD+ present to pick up electrons. NADH and FADH2 that were produced during glycolysis and the citric acid cycle are converted back into NAD+ and FAD after the electron transport chain. In Whenabsence of oxygen, the electron transport chain can’t run because there is no oxygen to act as the final electron acceptor. This means that the ETC will not be accepting electrons from NADH as its source of power, so NAD+ will not be regenerated. In order for the cell to continue to generate any ATP, NADH must be converted back to NAD+ for use as an electron carrier.

A. Make a table comparing the three main events of aerobic cellular respiration: glycolysis, Kreb's Cycle, and electron transport chain. For each stage list the input molecule, the products (including any energized electron carriers, NADH and/or FADH), the number of ATP generated in each stage for every one glucose molecule that begins the process, and the location in the cell.
