AP Biology Study Guide for Unit Test Covering Metabolism, Photosynthesis, and Cellular
Respiration
Metabolism (Ch 8) –
Please be sure you know:
1. The types of pathways. Types of energy.
2. What is metabolism?
3. Anabolism, Catabolism, Catalysis
4. Laws of Thermodynamics
5. Entropy
6. Endergonic, Exergonic, Endothermic,
Exothermic
7. Purpose of ATP
8. Enzymes, what do they do? How do they
work?
9. Competitive, non-competitive, inhibitor,
allosteric
Cellular Respiration (Ch 9) –
Please be sure you know:
1. Redox Reactions
 What does it mean when something is
reduced? Oxidized?
 What is an oxidizing agent? Reducing
agent?
 Be able to apply these to the cellular
respiration formula
2. Aerobic Respiration
 What molecules are involved? What
roles do they play?
 Types of phosphorylation, when they
occur, what is formed, how much
energy they yield.
A. Glycolysis
 What are the reactants? What are the
products? How are they formed?
 Where does it occur?
 What is the energy yield?
B. Citric Acid Cycle/Krebs cycle
 What are the reactants? What are the
products? How are they formed? What
is the energy yield?
 Where does it take place?
 Know some of the major molecules
(acetyl CoA, CoA)
C. Oxidative Phosphorylation
 What is it? What is formed?
 What is the energy yield?
 How does the ETC work? How are
ATP produced?
 What is Chemiosmosis? How does it
work?
3. Anaerobic Respiration
 What are the main types?
 What goes in? What comes out?
 Why does it occur?
Photosynthesis (Ch 10) –
Please be sure you know:
1. Light Reactions
 What are they composed of?
 Where do they occur?
 What are the reactants and the products?

reactions (and what are their jobs)?
 Know the role electrons make.
 Know the processes involved.
 What are the differences between linear
and cyclical phosphorylation?
2. Light Independent Reactions/Dark
Reactions
