B) has a decreased chemical reactivity; it is less likely to provide energy for cellular work. C) has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate. D) has less energy than before its phosphorylation and therefore less energy for cellular work. E) has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate. 56) Suppose the interior of the thylakoids of isolated chloroplasts were made acidic and then transferred in the dark to a pH-8 solution. What would be likely to happen? A) The Calvin cycle will be activated. B) The isolated chloroplasts will make ATP. C) Cyclic photophosphorylation will occur. D) Only A and B will occur. E) A, B, and C will occur.

57) Which of the following produces the most ATP when glucose (C 6 H 12 O 6 ) is completely oxidized to carbon dioxide (CO 2 ) and water? A) citric acid cycle B) fermentation C) glycolysis D) oxidative phosphorylation (chemiosmosis) E) oxidation of pyruvate to acetyl CoA 59) The surface of an integral membrane protein would be best described as A) completely covered with phospholipids. B) amphipathic. C) hydrophilic. D) exposed on only one surface of the membrane. E) hydrophobic. 62) What does cyclic electron flow in the chloroplast produce? A) glucose B) ATP C) NADPH D) A and B E) A, B, and C 64) Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate, an early step of glycolysis. In the presence of oxygen, an increase in the amount ATP in a cell would be expected to A) inhibit the enzyme and thus increase the rates of glycolysis and the citric acid cycle. B) activate the enzyme and thus slow the rates of glycolysis and the citric acid cycle. C) inhibit the enzyme and thus increase the rate of glycolysis and the concentration of citrate. D) inhibit the enzyme and thus slow the rates of glycolysis and the citric acid cycle. E) activate the enzyme and increase the rates of glycolysis and the citric acid cycle. 65) Where are the proteins of the electron transport chain located? A) mitochondrial matrix B) cytosol C) mitochondrial outer membrane D) mitochondrial inner membrane E) mitochondrial intermembrane space 66) The ATP made during glycolysis is generated by A) oxidation of NADH to NA. B) substrate-level phosphorylation. C) electron transport. D) photophosphorylation. E) chemiosmosis. 67) Testosterone functions inside a cell by A) coordinating a phosphorylation cascade that increases glycogen metabolism. B) acting as a signal receptor that activates ion-channel proteins. C) binding with a receptor protein that enters the nucleus and activates specific genes. D) becoming a second messenger that inhibits adenylyl cyclase. E) acting as a steroid signal receptor that activates ion- channel proteins.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
