Question

39) 39) An accumulation of NADII in a cell will regulate the citzic acid cycle. A) negatively B) positively tion of NADIH will have no effect on the citric acid cycle 40) 40) True or False?: P otoautotrophs do NOT contain mitochondria and therefore are unable to carry out acrobic respiration A) True B) False 41) energy is needed by the cell, which of the following is corect in repard to the metabolism of faty acids? B) Acetyl-CoA is peoduced, which decreases the rate of the Citric Acid Cycke C) Glucose 1-phosphabe is produced, which increases the rate of the Citric Acid Cycle Glucose 6-phosphate is produced, which decreases the rate of the Ctric Acid Cycle 6-phosphate is produced, which increases the rate of the Citric Acid Cycle D) 42) True or False?: In a person afflicted with cystic fibrosis, the airway remains hypoosmotic to the 42) ounding cells, preventing the movement of waner istse airway A) True B) False 43) The carbon that enters the carbon assimilation reactions of photosynthesisis to form triose 43) A) oxidized B) catabolized C) rodacod D) Both A and B E) Both B and C s that uses l ing that the44 process is otherwise similar to green plant photosynthesis, which of the following could repesent the overal reaction? A) 6 Co2+ 12 HzS CH1286 6 H2S+602 c) 6Co2+ 12 H2ColH12% 6 H2S+602 45 45) During what stage of oxygenic photosynthesis is 02 produced?
