Question

Question 15 2.5 pts Concerning post fixation synthesis of storage and transport sugars, which is FALSE? The recycling of inorganic phosphate, released from sucrose synthesis is necessary for the antiporter to work that brings triose phosphates out of the chloroplast. Starch is synthesized in the chloroplast as a major store of sugar for later use. Starch is synthesised when high amounts of triose phosphates form in the chloroplast, which can occur when factors prevent export of triose phosphates from the chloroplast. Sucrose is the primary transport sugar in plants, and can be formed in the cytosol of cells from triose phosphates exported from the chloroplast. The reimport of the inorganic phosphate into the chloroplast is necessary for the production of NADPH in the light-dependent reactions.
is thos correct

Answer 1

Correct answer is:Starch is synthesized in the chloroplast as a major store of sugar for later use. Starch is synthesised when high amounts of triose phosphates form in the chloroplast, which can occur when factors prevent export of triose phosphates from the chloroplast.

Reason Starch formation is no way affected by the transport of triose phosphates.The formation of starch does not occur because of the the export of the triose phosphates is prevented but because the remaining triose phosphates condenses and leads to formation of  starch and cellulose.
