Muscle pyruvate kinase (MPK)

Muscle pyruvate kinase (MPK) is an enzyme found in muscle cells that plays a key role in energy production. During exercise or muscle activity, MPK helps convert a sugar called phosphoenolpyruvate into pyruvate, releasing energy stored in the process. This energy is essential for muscle contractions and overall function. MPK's activity is regulated to meet the energy demands of the muscle, making it crucial for efficient performance during physical activity. In summary, MPK is an enzyme that helps muscles generate the energy they need to work properly.
