Question
A plant uses solar energy to make ATP and NADPH, which then drive the synthesis of carbohydrates in the leaves. At least one carbohydrate, sucrose, is translocated to nonphotosynthetic parts of the plant (stems, roots, flowers, and fruits) for use as a source of energy. Thus, ATP is used to make sucrose, and the sucrose is then used to make ATP. It would seem simpler for the plant just to make ATP and translocate the ATP itself directly to other parts of the plant, thereby completely eliminating the need for a Calvin cycle, a glycolytic pathway, and a TCA cycle.

Generation of ATP stops as soon as the sun and there is no practical way to store enough of it to meet the ongoing energy needs of the organism ATP would be a very way to move energy about, because it has a molecular weight of about daltons and contains high-energy phosphate bonds. Sucrose, in daltons and can give molecules of contrast, has a molecular weight of about ATP elsewhere in the plant.Explanation / Answer
Answer:
1.ATP is highly polar and would be difficult to move across the membranes.
2.Generation of ATP stops as soon as the sun rises,and there is no practical way to store enough of it to meet the ongoing energy need of the organism during the day.
3.ATP would be a very easy to move energy about because it has molecular weight of 500 Dalton and contains 3 high energy phosphate bond,sucrose in contrast has a molecular weight of 340 and can give 72 molecules of atp elsewhere in the plant.
