Chapter 10: Photosynthesis Multiple-Choice Questions 1) If photosynthesizing green algae are provided with CO2 synthesized with heavy oxygen (18O), later analysis will show that all but one of the following compounds produced by the algae contain the 18O label. That one is A) PGA. B) PGAL. C) Glucose. D) RuBP. E) O2. Answer: E 2) Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin Cycle? A) CO2 and glucose B) H2O and O2 C) ADP, Pi, and NADP+ D) electrons and H+ E) ATP and NADPH Answer: E 3) What are the products of the light reactions that are subsequently used by the Calvin Cycle? A) Oxygen and carbon dioxide B) carbon dioxide and RuBP C) water and carbon D) electrons and photons E) ATP and NADPH Answer: E 4) Where does the Calvin Cycle take place? A) Stroma of the chloroplast B) thylakoid membrane 1 C) cytoplasm surrounding the chloroplast D) chlorophyll molecule E) outer membrane of the chloroplast Answer: A 5) In any ecosystem, terrestrial or aquatic, what group(s) is (are) always necessary? A) autotrophs and heterotrophs B) producers and primary consumers C) photosynthesizers D) autotrophs E) green plants Answer: D 6) In autotrophic bacteria, where are the enzymes located that can carry on organic synthesis? A) Chloroplast membranes B) nuclear membranes C) free in the cytosol D) along the outer edge of the nucleoid E) along the inner surface of the plasma membrane Answer: E 7) When oxygen is released as a result of photosynthesis, it is a by-product of which of the following? A) reducing NADP+ B) splitting the water molecules C) chemiosmosis D) the electron transfer system of photosystem I E) the electron transfer system of photosystem II Answer: B 8) A plant has a unique photosynthetic pigment. The leaves of this plant appear to be reddish yellow. What wavelengths of visible light are being absorbed by this pigment? A) red and yellow B) blue and violet C) green and yellow D) blue, green, and red E) green, blue, and yellow Answer: B Use the following information to answer the questions below. 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. 9) What did Engelmann conclude about the congregation of bacteria in the red and blue areas? A) Bacteria released excess carbon dioxide in these areas. B) Bacteria congregated in these areas due to an increase in the temperature of the red and blue light. C) Bacteria congregated in these areas because these areas had the most oxygen being released. D) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths. E) Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis. Answer: C
