First pathway of photosynthesis
WebThe first step in photosynthesis is . A. Joining of three carbon atoms to form glucose. B. Formation of ATP. C. Ionization of water. D. Excitement of an electron of chlorophyll by a … WebThe first stage of the photosynthesis process is depicted by the light reaction. The light reaction involves converting solar energy to chemical energy in the form of ATP and NADPH. The chlorophyll pigment absorbs the sunlight energy and converts it into chemical energy in the form of electron charge carrier molecules.
