Select one:
a. It is used by the body during short-duration, low-intensity activities.
b. It is a complex carbohydrate that can be rapidly broken down into glucose
c. It is a form of glucose stored predominantly in the epidermal cells.
d. It is the chemical or substrate form in which most fat exist.

Answer 6

It is a complex carbohydrate that can be rapidly broken down into glucose

Question 7

What usually happens after 90 minutes of exercise?
Select one:
a. The amount of stored adenosine triphosphate (ATP) in the body increases.
b. The amount of available fuel for exercise from fats is exhausted.
c. The majority of muscle glycogen stores are depleted.
d. The oxidation of proteins predominates as the primary energy source.

Answer 7

The majority of muscle glycogen stores are depleted

Question 8

During glycolysis, in the presence of oxygen, pyruvic acid is converted into which important molecule in metabolism?
Select one:
a. Glucose-6-phosphate
b. Acetyl coenzyme A
c. Adenosine diphosphate
d. Propionyl coenzyme A

Answer 8

Acetyl coenzyme A

Which term refers to the assistance of amino acids in energy production during periods of starvation?
Select one:
a. The Kreb's cycle
b. Gluconeogenesis
c. The Cori cycle
d. Glycogenesis

Answer 9

Gluconeogenesis

Question 10

How does metabolism behave during EPOC?
Select one:
a. Increases
b. Fluctuates
c. Remains elevated
d. Remains unaffected

Answer 10

Remains elevated

Question 11

Bioenergetics—

Answer 11

The study of energy in the human body

Question 12

Metabolism

Answer 12

All of the chemical reactions that occur in the body to maintain itself. Metabolism is the process in
which nutrients are acquired, transported, used, and disposed of by the body.

Question 13

Exercise metabolism-

Answer 13

The examination of bioenergetics as it relates to the unique physiologic changes and
demands placed on the body during exercise

Question 14

Substrates

Answer 14

The material or substance on which an enzyme acts.

Question 15

Carbohydrates

Answer 15

Organic compounds of carbon, hydrogen, and oxygen, which include starches, cellulose, and
sugars, and are an important source of energy. All carbohydrates are eventually broken down in the body to glucose,
a simple sugar

Question 16

Glucose

Answer 16

A simple sugar manufactured by the body from carbohydrates, fat, and to a lesser extent protein; it serves
as the body’s main source of fuel.

Question 17

Glycogen

Answer 17

The complex carbohydrate molecule used to store carbohydrates in the liver and muscle cells. When
energy is needed, glycogen is converted into glucose for use by the muscle cells.
