Question

Which photosynthetic process will be lest affected by shorter periods of daylight?

A. The reaction at photosystem 1
B. The formation of ATP
C. The Calvin Cycle
D. The reaction at photosystem 2

Answer 1

C is your answer .-.

Answer 2

The correct option would be option C. The Calvin cycle.

Explanation:

The Calvin cycle is the set of chemical reactions that use chemical energy to produce glucose molecule and a 5 carbon molecule called RuBP. It takes place in the chloroplast of the cell.

The Calvin cycle also called as dark reaction or light-independent reaction because it takes place after the energy captured from the sunlight. The Calvin cycle does not directly depend on the light or photoperiodism (shorter or longer periods of daylight) so it will be least affected by a shorter period of daylight.

Thus, the correct option is C.
