In crassulacean acid metabolism (cam) plants 84) a) malate is stored in large vacuoles. b) the amount of carbon assimilated for each water molecule transpired is only 25 percent of that in c3 plants. c) stomata open during the day. d) carboxylation and decarboxylation reactions occur in the same location at the same time. e) co 2 is transported directly into mesophyll cells.

The correct answer is A malate is stored in the large vacuoles.

Explanation:

During CAM malate is synthesized from oxaloacetate by malate dehydrogenase enzyme.The so formed malate is stored inside large vacuoles during night.

    In the day time the guards cells of CAM plants get closed and malate is then discharged.The discharged malate is then transported into the chloroplast where the malate is converted to pyruvate and CO2.

    The CO2 then enters into the calvin cycle .

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

69 is the correct math for the amino acids
