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.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
