Cellular Respiration Quizzes

The main function of cellular respiration is to produce:

Identify the stage (or stages) of cellular respiration that occurs entirely outside of the mitochondria.

During which stage of cellular respiration is the majority of the ATP produced?

Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to CO2 with some net gain of ATP. Most of the energy from the original glucose molecule at that point in the process, however, is stored in the form of which of the following molecules?

Can energy be harvested by the cells from glucose without oxygen?

Carbon dioxide (CO2) is released during which of the following stages of cellular respiration?

Where are the proteins of the electron transport chain located?

Which of the following statements best describes the primary role played by oxygen in cellular respiration?

In chemiosmosis, what is the most direct source of energy that is used to convert ADP + i to ATP?

The enzyme phosphofructokinase (PFK) catalyzes a key step in glycolysis. PFK is inhibited by high levels of which of the following molecules?

The end product of glycolysis is

During glycolysis, two ATP molecules are "spent" in order to convert glucose to the highly reactive molecule:

The anaerobic breakdown of glucose is called:

Chemiosmosis in mitochondria directly results in the synthesis of:

From the beginning of glycolysis to the end of the Krebs cycle, what has the cell gained from the breakdown of each molecule of glucose?

Which parts of the mitochondria are directly involved in the synthesis of ATP during chemiosmosis?

When oxygen is present:

In the absence of oxygen, suppose a single yeast cell undergoes fermentation and uses 100 molecules of glucose. How many molecules of ATP will be generated?

In human muscle cells, fermentation (by itself) produces:

Which of the listed statements describes the results of the following reaction? C6H12O6+ 6 O2→ 6 CO2+ 6 H2O + Energy

Which of the following processes generates a proton-motive force in mitochondria?

Which stage of cellular respiration requires oxygen that you breathe?

In the presence of oxygen, the three-carbon compound pyruvate can be catabolized in the citric acid cycle. First, however, the pyruvate (1) loses a carbon, which is given off as a molecule of CO2, (2) is oxidized to form a two-carbon compound called acetate, and (3) is bonded to coenzyme A. Which of the following sets of products result from these reactions?

Which electron carrier(s) function in the citric acid cycle?

A cell has enough available ATP to meet its needs for about 30 seconds. What is likely to happen when an athlete exhausts his or her ATP supply?

Predict how many molecules of carbon dioxide are produced from the mitochondrial "burning" of one molecule of glucose?

Alcohol is a waste product produced by yeast in the presence of sugar and the absence of ________.

Why does yogurt taste sharp?
