Enzymes and activation energy

Référence de la vidéo 11936747
Enzymes and reaction activation energy. Animation showing the difference in reaction activation energy levels in the presence of an enzyme. The first stage of the animation shows the substrate (lower left) and the energy (red arrow) required to form the products (lower right). Without an enzyme, a higher activation energy (green flash) is needed. The second stage of the animation shows the lower activation energy needed when the enzyme is present. The presence of an enzyme can cause a large increase in the reaction rate, with some biochemical reactions taking place over a million times faster. For this animation with labels, see K004/2061.
