phosphofructokinase
Phosphofructokinase (PFK) is an important enzyme in the process of converting sugar into energy within cells. It acts as a key regulator in glycolysis, the pathway that breaks down glucose to produce energy. By controlling the speed of this process, PFK ensures that cells produce energy efficiently based on their needs. When energy levels are high, PFK slows down glycolysis, while low energy levels stimulate it. This regulation helps maintain the balance of energy production and consumption in the body, playing a crucial role in metabolism and overall cellular function.
