Describe how metabolism can be altered.

Describe how Addisons disease can be treated.

Explain how glucose is metabolized to yield ATP.

Insulin is released when food is ingested and stimulates the uptake of glucose into the cell. Discuss the mechanism cells employ to create a concentration gradient to ensure continual uptake of glucose from the bloodstream.

Discuss how carbohydrates can be stored as fat.

If a diabetics breath smells like alcohol, what could this mean?
