If a person’s ability to form steroids was destroyed, what function would be affected? Estrogen would no longer be produced in the body. Molecular hydrolysis reactions would stop functioning. The ability to produce insulin for glucose uptake would no longer exist. Cholesterol levels would keep increasing, causing cell death.

42. Patients with McArdle’s Disease lack an enzyme in their livers that catabolizes glycogen. Compared to an unaffected individual, what would you predict about the blood glucose levels of a patient with McArdle’s disease?A) Blood glucose levels would be lower because they cannot break down glycogen. B) Blood glucose levels would be lower because they cannot make glycogen. C) Blood glucose levels would be higher because they cannot make glycogen. D) Blood glucose levels would be normal, because glycogen is made up of amino acids. E) Blood glucose levels would be higher because they cannot break down glycogen.

37. What process(es) is/are required for phospholipids to flip-flop across the lipid bilayer?A) The process requires an enzyme called flippase. B) The process occurs spontaneously, requiring no energy. C) The process occurs spontaneously and requires the flippase enzyme. D) The process requires energy. E) The process requires energy and the flippase enzyme.

43. Altering the three-dimensional structure of an enzyme might A) prevent the enzyme from adding energy to a reaction. B) change the type of product that binds the enzyme’s active site. C) prevent the substrate from binding the enzyme’s active site.D) change the amount of energy needed for a reaction. E) change the type of product produced in the reaction.

Starch is used to store energy and cellulose is a structural polysaccharide. The key differences that explain these functions are cellulose with high branching aids strong structures, and starch with low branching makes for easy energy release. beta 1-4 and alpha 1-6 glycosidic linkage of starch can create branches, and alpha 1-4 linkages in cellulose creates strength. the unbranched structure of starch makes it easy to process for energy, and the branched structure in cellulose creates strong bonds. alpha 1-4 and alpha 1-6 glycosidic linkage in starch creates branching, and beta 1-4 linkages in cellulose creates unbranched structures.
