2
Q
What is a Catabolic Reaction?
A
Destructive; large organic molecules are broken down into smaller molecules; usually releases ATP/energy.
3
Q
What is an Anabolic Reaction?
A
Constructive; small precursor molecules are assembled into larger molecules; requires an input of energy/ATP.
4
Q

The amount of energy used by an animal within a specific period of time.
5
