Question

does dark reaction of photosynthesis occurs during night time only ?? answer fast and correctly !!!! URGENT...!

Answer 1

These reactions do not occur in the darkor at night. There is a light-dependent regulation of the cycle enzymes, as the third step requires reduced NADP; and this process would be a waste of energy, as there is no electron flow in the dark.

Answer 2

Dark reaction of photosynthesis does not require light. Both the light and dark reactions occur in the day. As dark reaction does not require light it doesn't meant it occurs at night it only requires products of light reaction like ATP and NADPH.
