... known as the active site producing new substrates(s) or products. Induced fit hypothesis: The attraction of the substrate and enzyme form an enzyme-substrate complex. It was originally referred to as the Lock and Key Enzyme Theory. The current theory suggests that the enzyme molecules are in an inactive form. To become active they must undergo a slight change in structure to more specifically accommodate the substrate(s). It is said to be "induced to fit" the substrate. Think of way your hand changes shape slight when you shake a person's hand. (Reference 1 ) Factors affecting rate of reaction: Effect of temperature on enzyme: As the temperature increase in an enzyme catalyzed reaction the rate of reaction also increases. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%. Variations in reaction temperature as small as 1 or 2 degrees may introduce changes ...
