Chapter 6: Metabolism: Energy and Enzymes

Learning Outcomes

After studying this chapter, you should be able to accomplish the following outcomes.

Cells and the Flow of Energy

1. State and apply two energy laws to energy transformations.

2. Give reasons why ATP is called the energy currency in cells.
3. Give examples to show how ATP hydrolysis is coupled to energy-requiring reactions.

4. Describe a metabolic pathway and how they function.
5. Explain how enzymes lower the energy of activation and speed chemical reactions.
6. List conditions that affect enzyme speed.
7. Explain how a cell can use enzyme inhibition to regulate metabolism.

8. Describe how chloroplasts and mitochondria both use redox reactions, an electrons transport chain, and chemiosmosis to produce ATP.
