Question

Several transport steps are involved in the movement of photosynthate from the chloroplasts. Following are certain statements regarding the transport of photosynthate: A. Pentose phosphate formed by photosynthesis during the day is transported from the chloroplast to the cytosol, where it is converted to sucrose. . B. Carbon stored as starch exits the chloroplast at night primarily in the form of maltose and is converted to sucrose in cytosol. C. During short distance transport, sucrose moves from producing cells in the mesophyll to cells in the vicinity of the sieve elements in the smallest veins of the leaf. D. In the process of phloem loading, sugars are transported into phloem parenchyma cells. Which one of following combinations of above statements is correct?
