Question 1

What is acetyl CoA?

Answer 1

Co-enzyme (enzymes that assist regular enzymes in chemicals reactions)

Question 2

What are electron acceptors?

Answer 2

Small organic molecules that accept electrons from other molecules

Question 3

What are electron carriers?

Answer 3

Small organic molecules that carry electrons from one molecule to another

Question 4

What is oxidation?

Question 5

What is proton gradient?

Answer 5

When a higher gradient of protons exists outside the inner membrane of the mitochondria than inside the membrane

Question 6

What is a redox reaction?

Question 7

What is reduction?

Answer 7

The process that allows a compound or molecule to gain electrons.
