A) stroma b) photon. D) reduced by the addition of carbon dioxide to the atmosphere, since carbon dioxide removes excess heat from the Earths surface and reflects it back into space. a) The light reactions occur in the thylakoid membranes, while the Calvin cycle occurs in the stroma. A) concentrated in a zone of leaf tissue called the mesophyll. What important fact does this argument ignore? Produces molecules of FADH2: CAC 19) The light reactions occur in the ________, while the Calvin cycle occurs in the ________. E) The principal electron carrier in photosynthesis is NADPH; the principal electron carrier in respiration is NADH. Which part of the ATP molecule breaks free of the rest when an ATP molecule is used for energy? D) ultraviolet. the energy in CO 2 is used to produce ATP and NADPH. c) stroma . D) methane. This is why plants need to take in carbon dioxide. It has increased from the pre-industrial level of 280 mol mol -1 in 1750 to c. 400 mol mol -1 at present and is expected to increase to c. 900 mol mol -1 by the end of the 21st century. NADPH is an electron carrier that picks up electrons in the light reactions and releases them in the Calvin cycle. It is acidic, and its concentration is in continual flux as a result of its utilization by aquatic plants in photosynthesis and release in respiration of aquatic organisms. A) H2O Plants appear green as they absorb these colors and reflect mostly green light. 36) Clusters of light-gathering pigments in a photosystem d) Photosystem I functions first in the sequence of steps a) Each preferentially absorbs slightly different wavelengths of light. Any substance that inhibits the transportation of oxygen from the lungs affects _____________. C) cytoplasm . A) The greenhouse effect is reduced by deforestation. d. Malleus C) absorption of photons by chlorophyll b He placed a stopper on each test tube and placed them all in the dark for 24 hours. C) eat other organisms that use light energy to make food molecules. A) cyanobacteria in freshwater and marine ecosystems B) grizzly bears in Alaska C) bacteria in our mouth D) fungi growing in the refrigerator E) mushrooms growing on the side of a dead tree, A) cyanobacteria in freshwater and marine ecosystems, What is the likely origin of chloroplasts? 46) The chloroplast ATP synthase At the same time other chemical changes may occur, which form additional colors through the development of red anthocyanin pigments. . Water that is filtered out of the blood by the kidneys is returned to the body through the action of aquaporins. Normal human gametes carry ____ chromosomes. If the rate of photosynthesis increases, the amount of carbon dioxide in the environment will decrease, and vice versa. . If the rate of photosynthesis increases, the amount of carbon dioxide in the environment will decrease, and vice versa. Less ATP is made under anaerobic conditions, so more glucose must be consumed to produce an equivalent amount of ATP. Figure 5.5 Photosynthesis uses solar energy, carbon dioxide, and water to release oxygen to produce energy-storing sugar molecules. B) couples the flow of H+ to the phosphorylation of ADP. E) The release of energy by the excited electron can be as heat, light, or fluorescence. A plant that uses CAM photosynthesis is most likely to be successful in what type of environment?a. It occurs in presence of light so the term "photo" Here the plant uses carbon dioxide and it reacts with water to given glucose ATP and NADPH A) play a role in glucose synthesis by plants. Contain membrane folds called cristae, whereas chloroplasts contain disk-like vesicles in stacks called grana. A) glucose, ADP, NADP+ After reading the paragraph, answer the question(s) that follow. Carbon dioxide Plants get the carbon dioxide they need from the air through their leaves. D) The greenhouse effect will decrease the average temperature of the planet. E) found throughout the plant. C) CO 2 is needed to produce sugars in the Calvin cycle.
