In photosynthesis, atp and electrons from light reactions are used in
a. glycolysis
b. krebs cycle
c. oxidative phosphorylation
d. calvin cycle

d. Calvin cycle

Explanation:

During the light reactions or photochemical reactions of photosynthesis, chlorophyll molecules absorb sunlight and convert light energy into assimilatory power in the form of the electron carrier molecule nicotinamide adenine dinucleotide phosphate (NADPH) and the ATP.

The ATP and NADPH used as a source of energy to fix or reduce carbon dioxide into glucose.

The reduction of carbon dioxide to glucose occurs in the stroma of the chloroplast. The reactions of the conversions are called the Calvin cycle.
