Document Summary
The effect of the catalyst (enzyme) is to lower the free activation energy for the reaction. Raising the temperature raises the average energy of a molecules increases reaction rate. In contrast, the average free energy of a molecule remains the same in unanalyzed versus catalyzed reactions (conducted at the same temperature) Note: metals: iron, magnesium, manganese, cobalt, copper, zink. Coenzymes are derived from vitamins (acetyl coenzyme a) Coenzymes make up a part of the active site. The activity of some enzymes are under complex control. The affinity of the enzyme for substrate will affect the rate of an enzyme catalyzed reaction. Feedback inhibition refers to a situation in which the substances at the end of a long series of reactions inhibit a reaction at the beginning of the series of reactions. Inhibition= product is going to inhibit further movement through pathways. As adp accumulates, a certain pathway/ enzyme is activated.
