91) As a result of the cascade of electrons moving down the electron transport chain and leaving the light reactions A) NADP+ is reduced to NADPH. C) NADPH is reduced to NADP+. 92) Mitochondria transfer_ energy from energy into the chemical energy of ATP. A) food; light; chemical C) chemical; food; light 93) What is the main adaptive advantage of the C4 and CAM photosynthesis strategies over the C3 strategy? A) They allow the plant to fix carbon under conditions of low CO2. 94) Plant cells B) They allow the plant to fix carbon in cool conditions. C) They make it possible for the plant to use the Calvin cycle at night. D) They help the plant synthesize glucose efficiently under dry conditions. A) have mitochondria but do not have chloroplasts. B) have mitochondria and chloroplasts. C) lack mitochondria and chloroplasts. D) lack mitochondria but have chloroplasts. B) NADP+ is oxidized to NADPH. D) NADPH is oxidized to NADP+. 2. regeneration of RuBP 3. release of G3P to ATP; chloroplasts transform B) light; food; kinetic D) food; light; nuclear 95) Put the following steps of the Calvin cycle in the correct order: 1. carbon fixation 4. reduction A) 4, 1, 2, 3 B) 1, 3, 4, 2 96) Global warming due to the greenhouse effect may be A) of little concern, since it is part of the normal cycle for the planet. B) reduced by the burning of fossil fuels, which removes oxygen from the atmosphere. C) moderated by photosynthesis, which removes carbon dioxide from the atmosphere. D) made worse by photosynthesis, which adds carbon dioxide to the atmosphere. C) 1,2,3,4 D) 1, 4, 3, 2 97) Many of the regions of the world where hunger is prevalent are also regions with hot and dry climates. What types of agricultural crops would you suggest that these regions attempt to grow? A) C4 plants and CAM plants B) C3 plants and CAM plants, such as prickly pear and pineapple C) C3 plants and C4 plants, such as corn and sugarcane D) C3 plants, such as wheat and rice 98) Red algae are found in relatively deep water. In order for light to penetrate to these depths, it must be high in energy. Which wavelengths of light would you expect red algae to use? A) green B) yellow C) blue D) red 91) As a result of the cascade of electrons moving down the electron transport chain and leaving the light reactions A) NADP+ is reduced to NADPH.
