What does enzymes are highly specific mean?
“ase”
What is meant by the term metabolism?
What are the starting and end products of the following:
Pyruvate oxidation
Kreb’s cycle
Respiratory chain
Chemiosmosis
What is the purpose of cellular respiration?
Cytolysis
Plasmolysis
What are redox reactions?
Reduction
Oxidation
When does fermentation occur? What are the main end products?
Difference between aerobic and anaerobic respiration
Site of cellular respiration
NAD and FAD
Effect of heat and temperature on enzymes and enzyme activity
Final electron acceptor of respiratory chain
ATP synthase
Enzyme saturation

How is ATP formed?
IMPORTANT NOTE
Answers to study guide for chapter 7, question #2 should read The final electron acceptor
of the respiratory chain. The answer is oxygen.
Good luck.
