d. The formation of starch in plants involves assembling many G3P molecules, with or without further rearrangements. G3P is easier for a plant to store. e. Use the following figure and the stages labeled A, B, C, D, and E to answer the following questions. Figure 10.2 If ATP used by this plant is labeled with radioactive phosphorus, in which molecules will the ____ 206. radioactivity be measurable after one "turn" of the cycle? a. in B only b. in B and C only c. in B, C, and D only in B and E only d. e. in B, C, D, and E If the carbon atom of the incoming molecule is labeled with a radioactive isotope of carbon, where ____ 207. will the radioactivity be measurable after one cycle? a. in C only b. in B, D, and E only c. in C, D, and E d. in A, B, and C in B and C e.

E only In metabolic processes of cell respiration and photosynthesis, prosthetic groups such as heme and ____ 209. iron-sulfur complexes are encountered. What do they do? a. donate electrons b. act as reducing agents act as oxidizing agents c. d. transport protons within the mitochondria and chloroplasts e. both oxidize and reduce during electron transport The pH of the inner thylakoid space has been measured, as have the pH of the stroma and of the ____ 210. cytosol of a particular plant cell. Which, if any, relationship would you expect to find? a. The pH within the thylakoid is less than that of the stroma. b. The pH of the stroma is higher than that of the other two measurements. c. The pH of the stroma is higher than that of the thylakoid space but lower than that of the cytosol. d. The pH of the thylakoid space is higher than that anywhere else in the cell.
