Phototrophic organisms convert light energy into chemical energy in the form of ATP. Photosynthetic organisms (photoautotrophs) also use light energy to make both ATP and reduced electron carriers (NADH or NADPH), which are both required to reduce carbon dioxide (CO2) to carbohydrate (CH2O).
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.unlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.
