Explanation / Answer
75- The membranes of the mitochondrion appear to be derived from the membrane found in bacteria. Thus, the correct option is (c).
76- Pyruvate is the molecule is most of the energy of glucose stored at the end of glycolysis. Thus, the correct option is (a).
77- The terminal electron acceptor of the electron transport chain is O2. Thus, the correct option is (b).
78- The name of the process that results in the production of ATP as electrons pass down the electron transport chain is Oxidative phosphorylation. Thus, the correct option is (d).
79- The mitochondria ultimately generate and store the energy used to produce most of the ATP made during aerobic respiration, by generating an ionic (electrochemical) gradient. Thus, the correct option is (c).
80- ATP synthase is not a possible electron carrier. Thus, the correct option is (d).
81- In humans, after a glucose molecule has been fully metabolized by the aerobic respiration machinery, CO2 must be removed from the body and excreted. Thus, the correct option is (a).
82- Regarding ATP synthase, the false statement is: The c- and ?-units rotate. Thus, the correct option is (b).
83- From an evolutionary perspective, Phosphofructokinase is the one most likely evolved into being first. Thus, the correct option is (c).
84- Na+ /K+ --ATPase is not involved with electron transport during respiration. Thus, the correct option is (d).
85-The new mitochondria produced by fission from preexisting mitochondria. Thus, the correct option is (a).
86-The advantage do the cristae confer on the mitochondria is that they greatly increase the surface area for aerobic respiration machinery. Thus, the correct option is (b).
87- The membranes of the mitochondrion appear to be derived from the membrane found in bacteria. Thus, the correct option is (c).
88- An integral protein in the inner mitochondrial membrane is ATP synthase. Thus, the correct option is (c).
89 –The molecule is most of the energy of glucose stored at the end of glycolysis is pyruvate. Thus, the correct option is (a).
