1. What does ΔG of a metabolic reaction measure?
2. Which of the following does a catalyst change during a chemical reaction?
3. ATP is not the only molecule that can drive reactions. When ATP is depleted during exercise, muscle cells use phosphocreatine to drive the regeneration of ATP.
4. Which source of energy does active transport use?
5. Which is an anabolic process?
6. The sodium-potassium pump is an active transport pump that uses energy to pump potassium into cells and sodium out of cells. Why is ATP energy required?
7. Which definition best describes a cell's metabolism?
8. Which reaction can provide the energy needed to run an endergonic reaction?
9. Which process(es) can directly amplify signals in a transduction pathway?
10. What happens when protein kinase A (PKA) phosphorylates phosphorylase kinase in the epinephrine signal transduction pathway?
11. Which is a catabolic process?
12. Which reaction does a kinase catalyze in a signal transduction pathway?
