Photon photosynthèse

The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction 6 H2O + 6 CO2 + energy → C6H12O6 + 6 O2 where C6H12O6 is glucose (which is subsequently transformed into other sugars, starches, cellulo… WebWhat substances are the reactants in photosynthesis?

WebApr 24, 2024 · Photosynthesis is the process by which certain organisms, including plants, create sugars from the carbon dioxide in the air and the oxygen atom of water. The energy that drives this process comes from light. There are two phases of photosynthesis, the light reactions and the light-independent reactions, also called the Calvin cycle. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are … See more Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light. However, not all organisms use carbon dioxide as a … See more In the light-dependent reactions, one molecule of the pigment chlorophyll absorbs one photon and loses one electron.
