fotoszintézisében

Fotoszintézisében is a Hungarian term referring to the process of photosynthesis. Photosynthesis is the fundamental biological process by which green plants, algae, and some bacteria convert light energy into chemical energy. This chemical energy is stored in the form of glucose, a sugar molecule, which serves as fuel for the organism's metabolic activities. The primary inputs for photosynthesis are carbon dioxide from the atmosphere and water absorbed from the environment. Sunlight provides the necessary energy to drive the reactions. Chlorophyll, a pigment found in chloroplasts, plays a crucial role in capturing this light energy. During the process, oxygen is released as a byproduct, making photosynthesis essential for maintaining the oxygen levels in Earth's atmosphere. This complex biochemical pathway can be broadly divided into two stages: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle). The light-dependent reactions convert light energy into chemical energy carriers like ATP and NADPH, while the light-independent reactions use these carriers to fix carbon dioxide into organic compounds. Fotoszintézisében is therefore a cornerstone of most ecosystems, forming the base of the food chain and supporting life on Earth.
