Question
9) When oxygen is released result ollowing? as a result of photosynthesis, it Is a by-product of which of the A) reducing NADP* B) chemiosmosis C) splitting the water molecules D) the electron transfer system of photosystem I E) the electron transfer system of photosystem 1 10) During glyolysis, when glucose is catabolized to pyruvate, most of the energy of glucose is 10) A) used to phosphorylate fructose to form fractose-6-phosphate. B) stored in the NADH produced. C) transferred to ADP, forming ATP D) transferred directly to ATP E) retained in the pyruvate 11) When a molecule of NAD+ (nicotinamide adenine dinucleotide) gains a hydrogen atom (not a 11) hydrogen ion) the molecule becomes A) reduced B) oxidized. C) hydrogenated D) a reducing agent. E) redoxed Refer to Figure 9.2, showing the citric acid cycle, es a guide to ansuver the follooring questions, Aceryt CoA FAD Ketogletarate NADH Figure 9.2 12) How many molecules of carbon dioxide (CO2) would be produced by five turns of the citric acid 12) cycle? (Do not include the Preparatory Reactions in your calculation). A) 2 B) 10 C) 60 D) s E) 12Explanation / Answer
9. C. Splitting the water molecules. - Water molecules split into O2 + H+ ions
10. B. Stored in the NADH produced.
Totally 2 NADH will be produced by glucose in glycolysis. 1NADH is resbonsible to synthesis 3ATP molecule. So 6 ATP produced.
11. Reduced
12. 10
