Question

Which of the following statements is TRUE? Any of the macromolecule classes can be converted to any one of the others. Dehydogenase enzymes generate "leftover" electrons that can be salvaged by CO- enzymes and taken to the complexes of the ETS. Succinyl-CoA Synthetase has the ability to couple an inorganic phosphate onto a GDP molecule to create a GTP which can then create a new ATP by substrate-level phosphorylation. Amino acids are converted by hepatocytes into glucose via gluconeogenesis. Beta-oxidation of fatty acids creates Acetyl Co-A units that can drive Citric Acid Cycle Proteogenesis & Glycogenosis are what hepatocytes do during the "Absorptive State " a. 1, 2, 3 b. 1, 2, 4, 5 c. 1, 2, 4, 5, 6 d. 2, 3, 5, 6 e. 1, 2, 3, 4, 5, 6 The "default" condition of the nephron produces______volumes of_____urine. a. large: dilute b. small: concentrated c. large: concentrated d. small: dilute e. cannont be determined or does not exist Which of the following are products from the Glycolysis pathway? NADH FADH_2 GTP ATP Pyruvate CO_2 a. 1, 3, 6 b. 1, 2, 5 c. 2, 4, 5, 6 d. 1, 4, 5 e. All of the above The hypothalamus functions in the____. control of body temperature production of neurohypophseal hormones coordination of ANS control of thirst & hunger control of urine output control of the adenohypophysis a. 1, 2, 3 b. 2, 4, 5, 6. c. 2, 3, 5 d. 1, 2, 4, 6 e. 1, 2, 3, 4, 5, 6

Explanation / Answer

77. Option e is correct. Here all the statements are true.

78. Option a is correct. The nephron has the capacity to produce dilute or concentrated urines, according to water balance. The default is to produce dilute urine, but a countercurrent multiplier system can extracts large volumes of water to concentrate urine when water intake is inadequate.

79. Option D is correct. Glycolysis, literally meaning "to split sugar," is the initial step in any respiratory system. Glycolysis involves the breaking down of a sugar (generally glucose, although fructose and other sugars may be used) into more manageable compounds in order to produce energy. The net end products of glycolysis are two Pyruvate, two NADH, and two ATP.

80. Option e is correct. Hypothalamus is involved in all these activities.
