Chapter 10: Photosynthesis MULTIPLE CHOICE 1) Organisms that can exist with light as an energy source and an inorganic form of carbon and other raw materials A) are called photoautotrophs. B) do not exist in nature. C) are called heterotrophs. D) are best classified as decomposers. E) both C and D ANS: A PTS: 1 TOP: Overview 2) Which type of organism obtains energy by metabolizing molecules produced by other organisms? A) autotrophs B) heterotrophs C) decomposers D) B and C E) A, B, and C ANS: D PTS: 1 TOP: Concept 10.1 3) The early suggestion that the oxygen (O 2 ) liberated from plants during photosynthesis comes from water was A) first proposed by C.B. van Niel of Stanford University. B) confirmed by experiments using oxygen-18 ( 18 O). C) made following the discovery of photorespiration because of rubisco's sensitivity to oxygen. D) A and B E) A, B, and C ANS: D PTS: 1 TOP: Concept 10.1 4) If photosynthesizing green algae are provided with CO2 synthesized with heavy oxygen ( 18 O), later analysis will show that all but one of the following compounds produced by the algae contain the 18 O label. That one exception is A) PGA. B) PGAL. C) glucose. D) RuBP. E) O 2 . ANS: E PTS: 1 TOP: Concept 10.1 5) Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin cycle?

6) What is the primary function of the light reactions of photosynthesis?

A) stroma of the chloroplast B) thylakoid membrane C) cytoplasm surrounding the chloroplast D) chlorophyll molecule E) outer membrane of the chloroplast ANS: A PTS: 1 TOP: Concept 10.1 9) A plant has a unique photosynthetic pigment. The leaves of this plant appear to be reddish yellow. What wavelengths of visible light are not 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 violet ANS: A PTS: 1 TOP: Concept 10.2 10) During photosynthesis, visible light has enough energy to A) force electrons closer to the nucleus. B) excite electrons. C)
