Question
25. During the Calvin cycle, plants: A) Fix CO2 into sugar B) Create ATP C) Oxidize H20 to oxygen. D) Convert solar energy to chemical energy 26. The majority of ATP in aerobic respiration is produced by: A) The Krebs cycle. B) Glycolysis. C) The electron transport chain. D) Photolysis 27. During cellular respiration, sun energy stored inis converted to chemical energy A) CO2 B) Yucca C) NAD D) glucos E) ATP 28. Eukaryotic cells require oxygen to: A) Serve as an electron acceptor in the electron transport chain B) Perform fermentation. C) Breathe. D) D) Enter the Krebs cycle as an intermediate. E) Start glycolysis. 29, , the Krebs cycle occurs in the , and the Glycolysis occurs in the electron transport chain occurs in the A) Mitochondria; mitochondria; mitochondrial B) Cytoplasm; cytoplasm; plasma C) Mitochondria; cytoplasm; plasma E) Cytoplasm; mitochondria; plasma 0. Which of the following statements concerning the electron transport chain is false? A) The final electron acceptor is oxygen. B) Each NADH yields three ATP molecules C) Each FADH2 yields two ATP molecules. D) The electron transport chain will work whether oxygen is present or not. 31. What product(s) do plants produce during photosynthesis that is/are used by humans and other animals? A) Oxygen 8) Oxygen and glucose C) Carbon dioxide D) GlucoseExplanation / Answer
Answer 25) in all oxygenic photosynthetic organisms, CO2 reduction and fixation occurs through carbon fixation cycle called Calvin cycle and takes place in the stroma of chloroplasts
Answer 26)the answer of the above question is electron transport chain because 32 ATP are produced during this stage.
Answer 27) the answer of the above question is glucose that is D because sun energy is stored in the form of food that is glucose which is then converted in to chemical energy for other purpose .and process was done by chlorophyll molecule present in chloroplast.
AnseAn 28)In eukayotic organism oxygen serve as a electron acceptor in electron transport chain for making Chemical energy known as ATP.
Answer 29) the answer of the above question is D that is glycolysiz occur in cytoplasm and kren cycle and ETC occur in mitochondria and mitochondrial membrane.
Answer 30)option D is wrong because if oxygen is not present than the ATP formation will not occur.
Answer31)end product of photosynthesis is glucose and oxygen . Which is option B.
