Assignment #3 Chapter 3

1. Define the terms aerobic and anaerobic.
A: Aerobic – Oxidative formation of ATP by the use of O2.
Anaerobic – Formation of ATP via the PC pathway and glycolysis that doesn't involve the use of O2. (Exercise Physiology Theory and Application to Fitness and Performance by Scott K. Powers & Edward T. Howley pg 29)

2. Discuss the function of glycolysis in bioenergetics. What role does NAD play in glycolysis?
A: Glycolysis is an anaerobic pathway used to transfer bond energy
from glucose to rejoin Pi to ADP. NAD is the hydrogen acceptor. (p 29 & 30)

3. How is bioenergetics controlled? What are rate-limiting enzymes and how do they operate?
A: Regulation of one or more enzymes in a biochemical pathway would provide a means of controlling. A rate-limiting enzyme is one enzyme in a metabolic pathway that determines the speed of the particular metabolic pathway......
