How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of both energy intermediates in photosystems I and II? Group of answer choices Electron flow rate can be increased, increasing both ATP and NADPH production. Plants often increase the amount of NADP reductase, thereby increasing NADPH production to match ATP output. Increase the electrochemical gradient for H+ across the thylakoid membrane, producing more ATP but not NADPH. Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH. More pigment can be rapidly created for greater photosynthetic capacity, producing equal amounts of ATP and NADPH.

Answer:

Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH.

Step-by-step explanation:

A Calvin Cycle is defined as a process by which various plants and algae takes carbon dioxide from the air and turns it into sugar, the food which the food autotrophs needs to grow. The Calvin cycle is required for every living being on earth to survive.

Both the ATP and the NADPH are required by the Calvin cycle. It occurs in the chloroplast stroma of the plants. Calvin cycle uses more amount of ATP than the NADPH and produces roughly same amount of both the energies. Photosynthesis may revert from the noncyclic to the cyclic electron flow and it produces more ATP than NADPH.
