ATP d. vaporized water Photosynthesis uses sunlight to convert water and carbon dioxide into a. oxygen. b. high-energy sugars c. ATP and oxygen. d. oxygen and high-energy sugars Which region of the visible spectrum is not absorbed well by chlorophyll? a. blue b. violet c. green d. red Which is not a component of Aerobic respiration? a. Carbon dioxide b. Lactic Acid c. NADH d. ATP Which of the following is NOT a step in the light-dependent reactions? a. High-energy electrons move through the electron transport chain. b. Pigments in photosystem II absorb light. c. ATP synthase allows H^+ ions to pass through the thylakoid membrane. d. ATP and NADPH are used to produce high-energy sugars. The Calvin cycle is another name for a. light-independent reactions. b. light-dependent reactions. c. photosynthesis. d. all of the above. If carbon dioxide is removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars? a. More sugars will be produced. b. Fewer sugars will be produced. c. The same number of sugars will be produced but without carbon dioxide. d. Carbon dioxide does not affect the production of high-energy sugars in plants. The amount of ATP produced from one molecule of glucose during aerobic respiration is: a. 4 b. 2 c. 28-30 d. 36-38Explanation / Answer
ANSWER:
18- The gas being collected is - (a) Oxygen
This is because the plant is kept in brighter sunlight. During this, the process of photosynthesis occurs. The plants taken in carbon dioxide and water to form glucose and release the oxygen gas. Which is then collected by the student.
19. Photosynthesis uses sunlight to convert carbon dioxide and water to convert to : (d) - oxygen and high energy sugars.
Because photosynthesis is a process in which the plants use carbon dioxide and water to form glucose and release the oxygen in presence of sunlight.
20. Chlorophyll II does not absorb : (c) Green portion of the visible light.
This is because most of the plants are green in color because of chlorophyll pigment. Only the color which is reflected appears to the human eyes. The chlorophyll does not absorb green color hence it reflects the green portion of visible light which makes the plants appear green.
21. The (b) : Lactic acid is not a component of aerobic respiration.
This is because the Lactic acid is produced during the anaerobic respiration which occurs in absence of oxygen.
22. Out of the following, the step (d) ATP and NADPH are used to produce high energy sugars does not occur in the light dependent reactions.
23.The Calvin cycle is another name for the
(a) Light independent reaction
This is because it occurs in the absence of sunlight in the stroma region of chlorophyll.
24. If the carbon dioxide is removed from plants environment , the (b) fewer sugars will be produced.
This is because the CO2 is one of the reactants which get converted to high energy sugar glucose during the photosynthesis process.
25. The amount of ATP produced from one molecule of glucose during aerobic respiration is (d) 36-38
