Detailed explanation-1: -Light reaction occurs inside thylakoids. The function of this phase is to produce NADPH and energy-rich ATP molecules.
Detailed explanation-2: -ATP, NADPH, and oxygen are the products of the light reactions, while glucose is the product of the dark reactions.
Detailed explanation-3: -Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.
Detailed explanation-4: -Light energy is used by photosynthetic organisms (photoautotrophs) to produce both ATP and reduced electron carrier (NADPH). ATP, NADPH, and O2 are the three products of photosynthesis’ light reaction.
Detailed explanation-5: -Cell Metabolism During photosynthesis light energy is used to split water, generating O2 and electrons that are then used to produce the ATP and NADPH required for carbon fixation.
