Chapter 9 True/False Questions

Without the Krebs cycle, the electron transport chain would produce very few ATPs.

True

In prokaryotes, the electron transport chain is located in the inner membrane of the mitochondria.

False

The first few seconds of intense exercise use up the cell's stores of fat.

False

The reactants of photosynthesis are the same as the reactants of cellular respiration.

False

If carbon dioxide is not present, the pathway labeled C in Figure 9-1 usually will not occur.

False

Cellular respiration releases energy by breaking down glucose in the presence of carbon dioxide.

False

During photosynthesis, energy is stored in the form of fats.

False

Either cellular respiration or fermentation can be used to release energy, depending on the presence of carbohydrates.

False

During the course of a long race, a person's muscle cells will use both cellular respiration and lactic acid fermentation to produce ATP.

True

If an animal cell stops carrying out cellular respiration, it will die.

True

If you swim aerobically for 30 minutes, your body has probably started to break down stored molecules, such as fats, for energy.

True

NADH and FADH2 carry electrons from the Krebs cycle to the electron transport chain.

True

The Krebs cycle releases energy in the form of ATP.

True

The products of glycolysis are 2 ATP, 2 NADH, and 2 pyruvic acid molecules.
