Chapter 3 Flashcards
1
Q
What is bioenergenetics?
A
The energy pathways of metabolism
2
Q
Energy from catabolic reactions is used to drive anabolic reactions through which which intermediate molecule?
A
Adenosine Triphosphate (ATP)
3
Q
What are the three energy systems that exist in the body to replenish ATP?
A
- Phosphagen system (anaerobic)
- Glycolysis (two types; fast & slow; both are anaerobic)
- Oxidative (aerobic)
4
Q
What is the primary energy system of ATP for short-term, high intensity activities?
A
Phosphagen system (anaerobic)
5
Q
The phosphagen system relies on energy from the chemical reactions of which two phosphagens?
A
- ATP
- Creatine Phosphate
6
Q
Why can’t the phosphagen system supply enough energy for continuous, long-duration activities?
A
Because ATP and creatine phosphate are stored in the muscle in small amounts
