The pentose phosphate pathway is quite active in adipose tissue. Why? Explain how this pathway complements lipogenesis with the use of an example (such as a person eating chocolate)

Pancreatic β cells express a receptor for fatty acids. Fatty acid binding to the protein appears to stimulate insulin secretion. Does this phenomenon make metabolic sense?

Lactose intolerance is caused by reduced production of the enzyme lactase.  A variety of digestive system problems, such as celiac disease and Crohn’s disease) can also lower the production of lactase.  If an individual produces low levels of the enzyme lactase, explain why they might be able to tolerate eating dairy products that contain lower levels of lactose (e.g., hard cheeses, feta cheese, and cottage cheese), but will not be able to tolerate foods with high levels of lactose (e.g., milk).

What is the name of the enzyme that produces acetyl-CoA? What is the name of its major inhibitor?   If this inhibitor is active, how will carbohydrate metabolism be affected?  Be specific.  (The word metabolism isn’t specific.)
