What does temperature do to enzyme activity?

WebMost enzymes will become denatured at very high temperatures. Although increased temperatures can cause enzymes to work more quickly, if the temperature gets too high the enzyme stops working. If the temperature around an enzyme gets too high, the enzyme loses its shape, which is known as denaturation, and ceases to work. WebThus too much heat can cause the rate of an enzyme-catalyzed reaction to decrease because the enzyme or substrate becomes denatured and inactive. Optimum Temperature.
