So increasing the temperature will increase the rate until we go up to this optimal temperature. And by increasing it further, we see that our activity of that enzyme, which is the Y axis, will jar, will drop sharply. Now, this is basically exactly why it's dangerous to have a fever. Because when our body temperature increases, we can basically damage our proteins, our enzymes found in the body. Now ironically, this is also a mechanism by which our body kills off bacterial cells. So when we're sick, the mechanism by which our body kills off the bacterial cells is by increasing the temperature of our body.
