Chapter 9: Cellular Respiration

Question 1

The amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius.

Answer 1

Calorie

Question 2

A pathway that releases only a small amount of energy. If oxygen is present, it leads to two other pathways that release a great deal of energy. If oxygen is not present, it is followed by a different pathway.

Answer 2

Glycolysis

Question 3

The process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.

Answer 3

Cellular Respiration

Question 4

Each accepts a pair of high-energy electrons. It helps to pass energy from glucose to other pathways in the cell.

Answer 4

NAD+

Question 5

It releases energy from food molecules by producing ATP in the absence of oxygen.

Answer 5

Fermentation

Question 6

It is said to be this because fermentation does not require oxygen.

Answer 6

Anaerobic

Question 7

They are said to be this because the pathways of cellular respiration require oxygen.

Answer 7

Aerobic

Question 8

It is the second stage of cellular respiration. In the presence of oxygen, pyruvic acid produced in glycolysis passes to the second stage of cellular respiration.

Answer 8

Krebs Cycle

Question 9

It uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.

Answer 9

Electron Transport Chain
