1.	Question : RuBP carboxylase, PEPcase, pyruvate dehydrogenase, ATPase, cytochromeoxidase, hexokinase, lactate dehydrogenase. Select/choose enzymes fromthe list above whichare involved in (a) Photosynthesis (b) Respiration (c) Bothin photosynthesis and respiration
Answer» Solution :RuBP Carboxylase : It is useful in dark reaction which does fixation of `CO_(2) i n C_(3)` pathway. PEPcase : It is useful for fixation of `CO_(2)` in photosynthesis in `C_(4)`pathway. SO 4C oxalo acetateis formed. Pyruvate : It is useful in aerobicrespiration, whichforms Acetyl. CO-A from pyruvic acid Pyruvic acid + Co-A + NAD`+ UNDERSET("Pyruvate dehydrogenase ")overset(MG^(+2))to "Acetyl "Co-A + CO_(2) + NADH + H^(+)` ATPase : It is useful in both respiration and photosynthesis. In both processes, it is associated with proton pump in electron transport system . ATP is formed by ATPaseby transportof proton. Cytochrome oxidase : It is ALSO useful in respiration and photo synthesis. It is an `e^(-)` carriers substance. Hexokinase : It is useful in glycolysisin respiration. By the glucose 6 phosphate is formed from glucose during that one ATP is used. Lactate dehydrogenase : It is useful in anaerobic respiration . eg. Lactobacillus Pyruvic acid + NADH ` underset("dehydrogenase ")overset("Lactate") to C_(3) H_(6) O_(3) + NDA`
