Bess [88]

Answer:

<u><em>This is because the enzymes might work best at higher temperature than 37 degrees Celsius. Increase in temperature will increase the catalysis of the reaction.</em></u>

<em>When the temperature is increased, the molecules possess greater kinetic energy. This will allow more substrate and enzymes to collide. As a result, there will be more enzymes taking place in the reaction which will cause the rate of the reaction to increase.</em>

<em></em>

However, if the temperature goes too high, then the shape of the active site of the enzymes will get changed. The enzyme will deactivate and the reaction will stop.
