HomeCellular Respiration Quiz Quiz on Cellular Respiration and Photosynthesis 1. In non-cyclic photophosphorylation,water splitting refills 'electron hole' in PS II and the site of water splitting is stroma grana thylakoid membrane thylakoid lumen chloroplast membrane 2. During respiration,incomplete breakdown of C6H12O6 into 2 pyruvate molecules occurs in cristae cytosol outer mitochondrial membrane inner mitochondrial membrane mitochondrial matrix 3. All the following statements on C4 plants are true except C3 cycle is present in C4 plants RuBP is the initial CO2 acceptor photorespiration is negligible in C4 plants CO2 fixation occurs at two sites The first product formed is Oxaloacetic acid 4. The number of NADH molecules produced per glucose molecule in Krebs cycle is 8 6 4 2 1 5. Which of the following process in cellular respiration is independent of oxygen concentration? Oxidative phosphorylation electron transport chain Krebs cycle Embden-Meyerhof pathway Chemiosmosis 6. The proton channel; cytochrome b6 f complex of photosynthesis is analogous to respiratory complex cytochrome bc1 cytochrome c oxidase NADH-CoQ reductase succinate dehydrogenase ATP synthase 7. During respiration,the energy released during electron flow is used to pump H+ into mitochondrial matrix cristae mitochondrial outer membrane mitochondrial intermembrane space cytoplasm 8. During photosynthesis,the energy released during electron flow is used to pump H+ into thylakoid membrane thylakoid space grana stroma chloroplast inner membrane 9. During respiration, Water is formed at the end of electron transport chain.What is the source of oxygen for the synthesis of water? C6H12O6 (glucose) CO2 Molecular O2 lactic acid (C3H6O3) pyruvic acid (C3H4O3) 10.
