respiration in that A) it involves an electron transport chain. B) energy is stored in the form of a proton (H+) concentration difference. C) generation of ATP is driven by a flow of protons (H+) through ATP synthase. D) the final electron acceptor is NADP+ and not oxygen. 15) Global warming due to the greenhouse effect may be A) moderated by photosynthesis, which removes carbon dioxide from the atmosphere. B) made worse by photosynthesis, which adds carbon dioxide to the atmosphere. C) reduced by the burning of fossil fuels, which removes oxygen from the atmosphere. D) of little concern, since it is part of the normal cycle for the planet. 16) NADH is also used by cells when making certain molecules. Based on your knowledge of NADH’s role in cellular respiration, what do you think NADH’s role is in biosynthesis of molecules? A) oxidizing molecules B) reducing molecules C) phosphorylating molecules D) dehydrating molecules E) none of the above 17) Put the following of the light reactions in the correct order: 1. Light excites an electron from photosystem I. 2. Light excites an electron from photosystem II. 3. Electrons reduce NADP+ to NADPH. 4. Electrons pass through an electron transport chain, which generates a H+ gradient used to make ATP. A) 1, 2, 3, 4 B) 1, 4, 2, 3 C) 2, 4, 1, 3 D) 2, 3, 1, 4 E) None of the above II. Conceptual Understanding You should understand and be able to thoroughly explain the following: How electrons move through the light reactions and how ATP and NADPH are formed The general sequence of the Calvin cycle How the Calvin cycle is related to the light reactions The similarities and differences between photosynthesis and cellular respiration; of chloroplasts and mitochondria
