Identify the method of regulation that is used in each example.

1. Athletes who train at high altitudes produce more of the protein erythropoietin (EPO) which results in increased red blood cell production.

2. In an animal cell, fats are primarily metabolized in mitochondria and synthesized in the cytoplasm.

3. Most adults have lactose intolerance unless they have a DNA sequence that increases their production of the enzyme lactase.

4. Insulin increases cellular uptake and storage of glucose.

5. Cholesterol inhibits HMG-CoA reductase, the rate limiting enzyme in cholesterol synthesis.
