NASM Chapter 8 Bioenergetics

Food is composed of which three compounds?

• ATP, glucose, and pyruvate

• Ketones, insulin, and ADP

• Carbohydrates, fats, and proteins

• Amino acids, ATP, and glycogen

What is the high-energy compound used by the body to do work?

• ATP

• ADP

• Glucose

• Fat

What does the first law of thermodynamics state?

• All energy is converted to heat.

• Energy can neither be created nor destroyed.

• Food increases metabolic rate.

• Metabolic rate is constant.

What is the name of the stored form of glucose?

• Pyruvate

• Glycolysis

• Triglycerides

• Glycogen

What is the ventilatory threshold 1 (VT1)?

• The point at which the body switches to using mostly fat as fuel for exercise

• The point at which the body uses mostly protein as fuel for exercise

• The point at which the body switches to using carbohydrates to provide at least half the fuel for exercise

• The point at which a person can no longer talk during exercise

What is the ventilatory threshold 2 (VT2)?

• The point at which the body shifts almost entirely to using carbohydrates for fuel

• The point at which it is still possible to talk during exercise

• The point at which the body uses mostly protein as fuel for exercise

• The point at which the body switches to using mostly fat as fuel for exercise

Which substrate provides nearly all the energy for activity at and above VT2?

• Fat

• Glucose

• Protein

• Ketone bodies

If someone specifically wanted to burn a lot of fat (not necessarily total calories), what type of exercise should they do?

• High-intensity exercise for less than 10 minutes

• Walking for 5 minutes

• Low- to moderate-intensity exercise for 30 to 60 minutes

• High-intensity exercise for 10 to 15 minutes

How many calories are in 1 pound of body fat?

• About 1,000

• About 3,500

• About 500

• About 5,500

What are the building blocks of body proteins?

• Amino acids

• Triglycerides

• Glucose

• Ketone bodies
