At very high temperatures, most enzymes do not increase the rate of the reactions that they requlate. which of the following is the most probable reason for this lack of enzyme activity?

Enzymes must have 'desired' temp. in order to properly react.

Explanation:

More heat means more kinetic energy, so molecules move faster. This makes the substrate molecules more likely to collide with the enzymes' active sites. The energy of these collisions also increases, which means each collision is more likely to result in a reaction. The rate of reaction continues to increase until the enzyme reaches its optimum temperature.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day
