Cell Respiration- Chapter 25
1. a. Why is chemical energy needed by cells? Chemical energy
is needed by cells to maintain homeostasis.
b. Define cell respiration. This is the process of harvesting chemical energy
Reactions of Cell Respiration
Types of Reactions and Equilibrium- Chapter 2
1. Describe the relationship between chemical bonds and
chemical reactions. How is energy involved? Chemical
reactions involve the breaking and forming of new bonds. Energy is stored in the bonds
Polarity and Solubility of Molecules- Chapter 2
1. Why is water the perfect medium to transport other
molecules? Because the structure of water allows it to dissolve other molecules
2. Explain why water molecules are polar? Water molecules ar
Acids and Bases- Chapter 2
Acids and Bases
1. Explain what makes a solution acidic.
The number of hydrogen ions determines the acidity of a solution.
2. Explain what makes a solution basic or alkaline.
The number of hydroxide ions determines the alkalinit
Regulation of Metabolism- Chapter 25
1. You have already seen that various hormones regulate
nutrient metabolism. Generally describe what happens
during each of the following states:
Absorptive State Nutrients originate from the digestive
Carbohydrate Metabolism- Chapter 25
1. a. What happens to most carbohydrates during digestion?
Carbohydrate is converted into glucose
b. What is the relationship between glucose and ATP production?
Glucose is broken down to produce ATP
Protein Metabolism- Chapter 25
1. a. Amino acids, produced by protein digestion, are not stored.
What happens to them instead? They are used to form new proteins
or oxidized to generate ATP
b. What happens to amino acids that are not immediat
Lipid Metabolism- Chapter 25
1. What are the products following hydrolyzation (digestion) of lipids? fatty
acids and glycerol
2. Within cells, what are two functions of fatty acids and glycerol?
- they can be oxidized to generate ATP.
Chemical Bonding- Chapter 2
1. Why are chemical bonds important? They are important because they
form the structure and function of many molecules in the body e.g.
proteins, carbohydrates etc
2. Explain the importance of the outer (valence) e
