What would happen to the light reaction and why if: RuBP carboxylase was inhibited, no CO2 was present, and if no sunlight is present?

Solution

Answer).Light reactions are the reactions in which the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. The energy which is formed during that reaction is transferred temporarily to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains.

Light  reactions occurs only in the presence of sunlight.IF no co2,no sunlight is present then there is no chance for the light reaction to take place.
