sejtmetabolizmust

Sejtmetabolizmus refers to the sum of all chemical processes that occur within a living cell. These processes are essential for maintaining life, enabling cells to grow, reproduce, respond to their environment, and repair themselves. Metabolism is broadly divided into two categories: catabolism and anabolism. Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process. This energy is often captured in the form of ATP (adenosine triphosphate), the cell's primary energy currency. Anabolism, conversely, involves the synthesis of complex molecules from simpler ones, requiring energy input.

Key metabolic pathways within cells include cellular respiration, which generates ATP from glucose and other fuel molecules, and photosynthesis, which occurs in plant and algal cells to convert light energy into chemical energy. Other vital processes include nutrient absorption, waste removal, and the synthesis of essential biomolecules like proteins, nucleic acids, and lipids. The regulation of sejtmetabolizmus is highly complex, involving intricate networks of enzymes and signaling pathways that ensure cellular functions are coordinated and optimized for the cell's needs and the organism's overall well-being. Disruptions in these metabolic pathways can lead to various diseases.
