Description

Chapter(10(Quiz( The process of photosynthesis probably originated ________. in plants in prokaryotes n fungi three separate times during evolution

Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin cycle? CO2 and glucose H2O and O2 ADP, Pi, and NADP+ electrons and H+ ATP and NADPH Which of the following statements best describes the relationship between photosynthesis and respiration? Respiration runs the biochemical pathways of photosynthesis in reverse. Photosynthesis stores energy in complex organic molecules; respiration releases energy from complex organic molecules Photosynthesis occurs only in plants; respiration occurs only in animals. ATP molecules are produced in photosynthesis but not in aerobic respiration. Chlorophylls absorb most light in which colors of the visible range? green and blue blue and red green and red violet and red

What event accompanies energy absorption by chlorophyll (or other pigment molecules of the antenna complex)? ATP is synthesized from the energy absorbed. A carboxylation reaction of the Calvin cycle occurs. Electrons are stripped from NADPH. An electron is excited. The proteins of the electron transport chain active in the light-dependent reactions are membrane proteins present in the thylakoid. are free proteins present in the thylakoid lumen. are considered to be part of the reaction center of photosystem I. absorb the same wavelengths of light as their associated chlorophylls.

Chapter(10(Quiz( How are the light-dependent and light-independent reactions of photosynthesis related? The products of light-independent reactions are used in light-dependent reactions. The products of light-dependent reactions are used in light-independent reactions. The products of light-independent reactions must be present for light-dependent reactions to take place. They are not related.

Bonus Question Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light. If you ran the same experiment as Engelmann without passing light through a prism, what would you predict? The results would be the same. The bacteria would be relatively evenly distributed along the algal filaments. The number of bacteria present would decrease due to an increase in the carbon dioxide concentration. The number of bacteria present would increase due to an increase in the carbon dioxide concentration. E) The number of bacteria would decrease due to a decrease in the temperature of the water....
