Depends on the enzyme I guess! As you're talking about the human body, I'll assume you mean human enzymes as there are enzymes that work at very high temperatures just fine. If an enzyme exceeds its optimum temperature, the molecules within its primary structure vibrate so much that the shape of the active site changes and it becomes 'denatured'. This means it can no longer bind its substrate (lock and key hypothesis) and will not function as required. This process can be reversed if cooled back down although the protein doesn't always reform into its original conformation. I like to think of an enzyme as a 'Pac-Man' shape with the mouth as the active site. If denatured, the mouth will not be the right shape anymore.

Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

High salt concentrations can also cause chemical bonds within the protein to break in a similar matter. Typically, enzymes function optimally in the environment ...
It would seem ideal to have a scenario in which all of an organism’s enzymes existed in abundant supply and functioned optimally under all cellular conditions, in all cells, at all times. However, this is not true for a variety of reasons. First, it would require a lot of energy to produce all an organism’s enzymes all the time. Also, cellular needs and conditions constantly vary from cell to cell, and change within individual cells over time. The required enzymes of stomach cells differ from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive organ cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so must the amounts and functionality of different enzymes.

Do you fully understand why enzymes have the best catalytic activity within a specific temperature range? It's reassuringly simple and we will explain more about the optimum temperature for enzymes in our handy guide.

As it turns out, the enzymes that are most affected by changes in body temperature are also often the enzymes that catalyze some of the more expendable bodily ...
The shape of an enzyme also depends on its temperature. When enzymes get too warm, they get too loose. And when they get too cold, then they get too tight. When they are just the right temperature, then they are just the right shape and the chemical reactions that they catalyze take place at the optimal rate and with the most ease. When the temperature is too hot, too cold, or unsteady, the enzymes will spend less time in their optimal shape which simply translates into having a less than optimal metabolism. An interesting example of how this works can ...Read the full article!
