Coenzyme Q10, or CoQ10, is just what its name implies: a coenzyme. Coenzymes are substances that work in tandem with enzymes to promote their activity. NAD+ or Coenzyme A, which are generated from vitamin B5, are another excellent illustration of a coenzyme that is extremely important in our systems. CoQ10 primarily works as a coenzyme in the electron transport chain and the citric acid cycle (also known as Krebs cycle), where it is crucial for producing ATP and obtaining useable energy from food. The fact that CoQ10 functions as an electron transporter may be more significant than its role as a coenzyme. Accordingly, CoQ10 takes up electrons in the electron transport chain and facilitates their movement so that ATP is eventually produced. Available In Pakistan
