question 37

Multiple Choice

Refer to the table below showing results of some researchers who exposed wheat plants to ¹⁴C-labeled carbon dioxide for various lengths of time in the light before extracting various compounds from leaves.The extracted compounds were separated using paper chromatography, and the amount of radioactivity for each spot on the chromatogram was measured for a specified duration of light exposure.The results for sucrose are shown in the table. In a control run, during which plants were kept in the dark, no radioactivity was incorporated into sucrose over a 25-hour time period.Which statement about sucrose is supported by these data?

• A) A plant can use sucrose as a source of energy during periods of darkness when photosynthesis shuts down.
• B) Sucrose is the form of fixed carbon that is transported from photosynthetic tissues to nonphotosynthetic tissues throughout the plant.
• C) G3P formed via the Calvin cycle can enter gluconeogenesis to form hexose phosphates and then sucrose in plant leaves.
• D) Glucose and fructose are monosaccharides that bond together to form the disaccharide sucrose.
• E) Sucrose serves as a source of fixed carbon that can be distributed throughout the plant.
