MCQ Test Welcome to your 9th Biology 1. In which process light energy is store in the form of bond energy : photosynthesis light reaction dark reaction respiratio Aerobic respiration needs free ............. . Carbon Nitrogen Oxygen None Which of these can enter into Krebs cycle? Glucose Pyruvic acid Citric acid Acetyl Co.A The visible portion of sunlight consist of ............... colours. Four Five Six Seven 249. Which stage of Aerobic respiration is involved in complete oxidation of pyruvic acid ? Krebs cycle electron transport chain Photolysis glycolysis 258. The compound that absorbs carbon dioxide is: K2H NaOH O2 H2O The last stage of aerobic respiration is: Electron Transport Chin glycolysis photolysis krebs cycle 260. The movement of water from a dilute solution to concentrated solution through a membrane is called as: Osmosis Active transport All of these Diffusion The reactions takes place on thalakoids of chlorophyll is: Light reaction Glycolysis Dark reaction Electron transport chain 256. Respiration is a……. type of reaction. catabolic acidic metabolic anabolic Fermenting powers of bacteria are used in making: Soya sauce Bread Cheese Cheese and yogurt 1. Photosynthesis is occur in chloroplasts while respiration takes place in : cytoplasm and mitochondria nucleus and cytoplasm nucleus cytoplasm 1. What are the final products of anaerobic respiration? CO2 + Lactic acid ethanol H2O ATP+H2O CO2 + Lactic acid When a plant was kept in darkness for many days, many days, its leaves turned yellow. Why? Leaves could not get oxygen and so there was no photosynthesis Leaves could not get light and so there was no respiration Leaves could not get oxygen and so there was no respiration Leaves could not get light and so there was no photosynthesis In which of the following steps of respiration, CO2 is produced? Glycolysis Krebs cycle Electron trransport All of these The clusters of photosynthetic pigments are called: Thylakoids Photosystems Carotenoids Chlorophyll a & b How many percent of the light falling on the leaf surface is absorbed: 5% 6% 7% 1% 1. Photosynthesis is a what kind of process ? anabolic redox metabolism catabolic 252. How many molecules of ATP are produced by each NADH in electron transport chain ? 3 4 5 2 Most of the energy during ATP formation escapes in the form of: Waves Bonds Heat Chemical ATP molecule was discovered by: Fritz Lipmann Calvin Karl Lohmann Hans krebs 251. During anaerobic oxidation of glucose , how many ATP molecules are gained as net profit ? ATP-1 ATP-2 ATP-3 ATP-4 1. How many ATPs are produced in aerobic respiration? 36 22 33 2 Time is Up!
