Metabolism and Digestion

What is a catabolic pathway?

What is an anabolic pathway?

What are the three ways to drive a thermodynamically unfavorable reaction?

1. Couple the reaction to a more favorable reaction (ex. ATP hydrolysis)

2. If the products of the reaction are rapidly removed, the reaction will be driven to the right

3. If the substrate builds up, the reaction will be driven to the right

Why is ATP the universal energy currency?

1. It is thermodynamically unstable

2. It is kinetically stable

3. High phophoryl transfer potential (actually intermediate between that of important phophoryl donors and acceptors)

How long can we power muscle contraction with available ATP supplies?

How is ATP replenished?
