WebThe basic chemical reaction for oxygenic photosynthesis is: CO 2 + 2H 2 O + photons → [CH 2 O] + O 2 + H 2 O. During photosynthesis, one molecule of carbon dioxide and 2 molecules of water are converted into molecular oxygen and some carbohydrate. Creating organic compounds from inorganic carbon is known more generally as “carbon fixation.”. WebJun 8, 2024 · Photosynthesis is essential to all life on earth. It is the only biological process that captures energy from outer space (sunlight) and converts it into chemical energy in the form of G3P ( Glyceraldehyde 3-phosphate) which in turn can be made into sugars and other molecular compounds. de shaw aptitude test for finance
