High specific gravity Small volume & very concentrated 6. pH of 4.5 a. 1, 2, 3 b. 1,3, 5, 6 c, 3,4,5 d. 1,3, 4,5,6 e. All of the above 90. Which of the following reactions liberates CO,? . PyruvateAcetyl-CoA 4. 5. socitrate a-ketoglutarate DHAP ? G3P 2. Suocinate Fumarate 3. Malate Oxaloacetate a. 1, 2, 3 b. 2,4, 6 c. 1,5, 6 d. 1, 2, 3, 5 e. 1,2, 3, 5,6 91. Starting with a GLUCOSE molecule and ending with ATP, indicate the correct chronological sequence that each of the following chemical reactions would occur in a cells normal metabolic processes. 1. Glucose phosphorylation by Hexokinase into Glucose-6-Phosphate 2. Pyuvate transformation into Acetyl-CoA by dehydrogenation&expulsion; of CO Isomerization of G-6-P into Fructose-6-Phosphate 4. Isocitrate changed into a-ketoglutarate followed then by transformation into Succinyl-CoA 5. Dihydroxyacetone phosphate Glyceraldehyde-3-phosphate 6. Nicatinamide adenine dinucleotide "passing" electrons to Complex I of the ETS 7. G-3.P Pi1,3 Bisphosphoglycerate (catalyzed by Triose Phosphate Dehydrogenase S. Cytochrome-c "passing" electons to Complex IV: Complex IV then "passing"electrons to O2 to make water 9. Phosphoenolpyruvate conversion to Pyruvate by Pyravate Kinase 10. ADP+P, Adenosine triphosphate via ATP Synthase action (oxidative phosphorylation) a. b. c. d. e. 1,2,3,4, 5, 6, 7,8, 9, 10 2,4, 6,8, 10, 1,3, 5, 7,9 1,2, 8,7, 4, 5, 3,9,10, 6 1,3, 5, 7,9, 2, 4, 6, 8, 10 2,3,4,5,6, 10, 9, 8,7,1 92. Which of the following statements are CORRECT? a. The ascending limb of the nephric loop is impermeable to water but extremely active in b. The active pumping of ions in the ascending limb results in a 200 mOsm/L difference in the filtrate is impermeable to water but extremely active in pumping ions e. Both a & bare desrigtive of wat s efe Curront Mtaliplier" ht establishes and maintains the tremendous medullary salt gradient d. All the above e. Only a & bExplanation / Answer
89. b ( 1,3,5,6) [the person is dehydrated so urine will be strong yellow or golden yellow due to high relative concentration urobilinogen, concentrated and scanty urine, high specific gravity. As the person is acidic, so kidney will try to compensate by filtrating H+ in the urine--> resulting in lower ph( normal urine pH 4.5 to 8)]
90. c( 1,5,6) [ In Kreb's cycle there are three steps where CO2 is released. 1 .from pyruvate to acetyl-CoA , 2. From Isocitric acid to alpha-ketoglutaric acid, 3. From alpha-ketoglutaric acid to succinyl CoA ]
91. d( 1,3,5,7,9,2,4,6,8, 10) [ Let me tell you the easy process choose the answer. From the question, it is clear that it is glycolysis +Kreb's cycle. The first step in the glycolysis is conversion of glucose into glucose -6 phosphatase by hexokinase, so 1 is first, then glucose -6phosphatase is isomerized into fructose-6- phosphatase----> then to glyceraldehyde, so option sequence is 1->3->5, so in the given answer only option D follows this rule, so answer is d]
92. d( all of the above) [ ascending loop is impermeable to water and active ion pumps are abundant there, the osmotic gradient in ascending and descending loop is the main mechanism of counter-current multiplier mechanism ]
