Photochemical phase of photosynthesis
WebPhotochemical phase of photosynthesis is also known as light reaction. It is responsible for the formation of high-energy chemical intermediates, ATP and NADPH, and it includes light absorption, water splitting and release of oxygen. It takes place in the granal thylakoids of chloroplasts. Production of assimilatory power in photosynthesis: It ...

WebPhotosynthesis is the process of conversion of light energy into chemical energy which can then be utilized by living organisms. It is a rather complex process which is carried out through various stages. Photosynthesis … WebCorrect option is A) Light reactions of photosynthesis which takes place in thylakoids membranes of chloroplast utilize sunlight and water to produce oxygen, ATP and NADPH. The energy from the sun is converted to ATP and NADPH which is later utilised in the dark reaction to produce organic compound glucose, hence organic compound is a byproduct ...

WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3. In the two other known pathways, C 4 and CAM (crassulacean acid metabolism), the C 3 pathway follows the fixation of CO 2 into oxaloacetate, a four-carbon acid, and its reduction to malate.
