Metabolism I

Question 1

1st law of thermodynamics

Answer 1

energy cannot be destroyed or created but changed from one form to another

Question 2

result of high ATP & low ADP

Answer 2

ATP-breakdown is low, less need for ATP production

Question 3

Result of low ATP and high ADP

Answer 3

ATP-breakdown is high, high need for ATP production

Question 4

Adenosine Triphosphate

Answer 4

phosphate group attached by “high-energy bonds”

Question 5

Where does energy come from to support re-phosphorylation of ADP to ATP?

Answer 5

• ATP-PCr (high energy phosphate system)
• Anaerobic glycolysis
• oxidation of glucose (or glycogen)
• oxidation of fatty acids
