Question 1

What is bioenergenetics?

Answer 1

The energy pathways of metabolism

Question 2

Energy from catabolic reactions is used to drive anabolic reactions through which which intermediate molecule?

Answer 2

Adenosine Triphosphate (ATP)

Question 3

What are the three energy systems that exist in the body to replenish ATP?

Answer 3

1. Phosphagen system (anaerobic)
2. Glycolysis (two types; fast & slow; both are anaerobic)
3. Oxidative (aerobic)

Question 4

What is the primary energy system of ATP for short-term, high intensity activities?

Answer 4

Phosphagen system (anaerobic)

Question 5

The phosphagen system relies on energy from the chemical reactions of which two phosphagens?

Answer 5

• ATP

- Creatine Phosphate

Question 6

Why can’t the phosphagen system supply enough energy for continuous, long-duration activities?

Answer 6

Because ATP and creatine phosphate are stored in the muscle in small amounts
