Cell Biology Questions

Which of the following does not occur during the third phase of glycolysis?

The inputs to glycolysis do not include:

Proteins can be broken down for energy. They are typically broken down into amino acids, which then enter cellular respiration via:

In a plant cell, all stages of cellular respiration are carried out in the cytoplasm.

A single molecule of glucose requires _____ "turns" through the citric acid cycle for its chemical energy to be completely harvested.

The final electron acceptor of the electron transport chain is:

During acetyl-CoA synthesis, pyruvate is:

When an electron is transferred from NADH to CoQ, NADH is __________________ and CoQ is _____________________.

You may be familiar with the story of Philippides, the famous Grecian who ran the first marathon and then died after completing his run. Based on what you know of aerobic respiration and fermentation, why might Philippides have died?

The majority of energy generated in the citric acid cycle is in the form of:

In eukaryotes, acetyl-CoA synthesis takes place in the:

By the time pyruvate is formed, most of the energy contained in glucose has been released.

ATP is not generated directly in the citric acid cycle; instead, an intermediate is first generated by substrate-level phosphorylation. The intermediate is:

Oxidation is the gain of electrons.

Imagine that you exhale after a deep breath. What are you not exhaling?

Once they have been processed through the citric acid cycle, the acetyl-CoA molecules from a single glucose molecule will produce:

In the first three stages of cellular respiration, the chemical energy in glucose is transferred to:

Excess glucose is stored in large branched molecules of:

The _____ forms of the electron carriers NAD+/NADH and FADH/FADH2 have high potential energy.

Which of the following is not an end product for an acetyl group that enters the citric acid cycle?
