Let’s say that a series of enzymatic reactions results in the conversion of glycogen (a polysaccharide stored in the liver) to glucose monomers (used in the bloodstream for energy). a. If negative feedback occurred in this pathway, how would enzymes in the pathway be affected, and how would the amount of glucose produced be affected?

b. If positive feedback occurred in this pathway, how would enzymes in this pathway be affected, and how would the amount of glucose produced be affected?

c. Is it more likely that the breakdown of glycogen is controlled by negative or positive feedback? Why? Relate your answer to homeostasis.
