Biomolecules

Question 1

Identify the products that fat is broken down into during catabolism

Answer 1

Fatty acids and glycerol

Question 2

Identify the product that proteins are broken down into during catabolism

Answer 2

Amino acids

Question 3

Identify the products that carbohydrates are broken down into during catabolism

Answer 3

Glucose

Question 4

What is the function of carbohydrates in the body?

Answer 4

Primary function: provides energy and stores energy

Question 5

What is the function of fats in the body?

Answer 5

Triglycerides:

• energy storage
• provides energy
• insulates and protects internal organisms

Phospholipids:
- protective barrier around each cell - part of membrane

Cholesterol:
- maintains integrity and fluidity/stabilization of cell membranes

Question 6

What is the function of proteins in the body?

Answer 6

Responsible for multiple physiological functions

e.g. enzymes, antibodies, blood proteins

Question 7

What is denaturation?

Answer 7

Structural change in proteins that results in the loss of their biological function

Question 8

How does temperature influence protein function?

Answer 8

High levels of thermal energy disrupt hydrogen bonds holding the protein together
- when bonds break, proteins unfold and lose their capacity to function properly

Question 9

How does pH influence protein function?

Answer 9

Change in pH will alter the charge of the protein, which in turn will alter protein solubility and shape
