20.(6 pts.)TheDG for the glycolytic pathway is -85 kJ/mol, whereas theDGº’ for the glycolytic pathwayis -35.5 kJ/mol.What accounts for the more favorableDG as compared toDGº’ for the glycolytic pathway?A.Cellular metabolite concentrations account for the more favorableDGº’ as compared toDB.Enzyme shift from T state to R state accounts for the more favorableDG as compared toDGº’.C.Cellular metabolite concentrations account for the more favorableDG as compared toDGº’.D.Enzyme turnover number andKmaccount for the more favorableDG as compared toDGº’.E.It is because enzymes alter the change in free energy, but not the equilibrium constant.G.
BIOC 384 Fall 2021 Exam 3KEYName________________________Preceptor/Team_____________21.(6 pts.)Infants express the enzyme lactase in their intestines to metabolizelactose.How manynetATP can be generated from lactose under anaerobicconditions by infants with high levels of lactase?Choose your answer in the box.22. (6 pts.)Match the biochemical process in list A with the type of enzymaticregulation in list B with regard to the control of glutamine synthetase activity by theenzymes glutamine synthetase adenylyltransferase and control of glutaminesynthetase adenylyltransferase activity by uridylyltransferase. Write your answers in column A from aàeand record. Choices in column B can be used once, more than once, or none at all.Column AColumn B_1___ a. binding of ATP1. allosteric control_4___ b. adenylylation2. subunit association_1___ c. binding of glutamine3. proteolytic cleavage_4___ d. uridylylation4. covalent modification_1___ e. binding of Pi23. (6 pts.)You are hiking the finger rock trail in the Catalina mountains and come across a rattlesnakecrossing the trail, which activates a physiological stress response. Choose the answer below that correctlyidentifies the a) hormone, b) a receptor that is activated by the hormone in part a, and c) the target enzymethat is activated in the downstream pathway identified by parts a + b. All three answers must be correct.
