Redoxháztartás

Redoxháztartás refers to the balance of oxidation and reduction reactions within a biological system. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. These processes are fundamental to many metabolic pathways, including cellular respiration and photosynthesis. In living organisms, redoxháztartás is crucial for energy production and the maintenance of cellular function.

Enzymes play a vital role in mediating redox reactions, often utilizing cofactors such as NAD+/NADH and FAD/FADH2. These cofactors act as electron carriers, transferring electrons between different molecules. Disruptions in redoxháztartás can lead to oxidative stress, a condition where the production of reactive oxygen species (ROS) overwhelms the body's antioxidant defenses. Oxidative stress is implicated in aging and various diseases.

Antioxidants are molecules that can neutralize ROS, thereby protecting cells from damage. The body produces its own antioxidants, and they are also found in dietary sources. Maintaining a healthy redoxháztartás involves a balance between pro-oxidants and antioxidants, ensuring that cellular processes can proceed efficiently without causing undue harm. Understanding redoxháztartás is essential for comprehending cellular metabolism and the mechanisms of disease.
