Proteins

Question 1

Function / Example of Structural Protein

Answer 1

Function - Provide Shape and Support
Example - Keratin

Question 2

Function / Example of Enzymes

Answer 2

Function - Speeds up Chemical Reactions in living things (biological catalyst)
Example - Catalyses

Question 3

Function / Example of Hormones

Answer 3

Function - Chemical messengers which send messages around the body in the bloodstream
Example - Insulin

Question 4

Function of Antibodies

Answer 4

Function - Part of the immune system. Produced by white blood cells and protect the body from microbes.

Question 5

What is an Enzyme and Its Functions?

Answer 5

• Biological Catalysts
• Speed up Chemical Reactions
• Found in All Living Cells
• Made up of Protein
• Can be Reused

Question 6

What Molecules do Enzymes Fit With?

Answer 6

Substrates

Question 7

What is an Active Site?

Answer 7

The area on an enzyme that binds its substrates. The shape of the active site is specific to the substrate.

Question 8

What is a Degradation Reaction?

Answer 8

Breaking down big molecules into small ones.

Question 9

What is a Synthesis Reaction?

Answer 9

Building up big molecules from small ones.

Question 10

What is “Optimum”?

Answer 10

When the enzyme is at its most active.

Question 11

What are Factors Affecting Enzymes?

Answer 11

If the temperature or pH changes beyond the optimum, the shape of the enzyme changes. This will affect the shape of the active site, meaning the enzyme will no longer work.
