The Sun! Most of the removed electrons and hydrogen ions ultimately are transferred to carbon dioxide (CO 2 ), which is reduced to organic products. Extra ATP required in C 4 photosynthesis for the CO 2 ‐concentrating mechanism probably comes from cyclic electron transport (CET). The amount of carbon dioxide in the air immediately surrounding the plant can fall when planting is very dense, or when plants have been photosynthesizing rapidly, especially in an unventilated greenhouse. Through the process of photosynthesis plants convert light energy into chemical energy. Photosynthesis is the process of converting light energy (E = h v) to chemical energy and storing it in the chemical bonds of sugar-like molecules.This process occurs in plants and some algae (Kingdom Protista). Analyzing requirements involves much more than merely writing down what the customer wants. In plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2 ), hydrogen ions (H + ), and electrons. 711 711 711 711 711 711 711 711 711 711 402 402 867 867 867 617 In photosynthesis, since two quanta are required for the formation of one molecule of reductant, either one or 2/3 quantum respectively are required for the formation of each molecule of ATP.
