List three different factors which influence the rate of enzyme activity and specifically explain each factor’s influence on enzyme activity.

Since enzymes are protein, they are very sensitive to environmental conditions.
The very nature of large 3- dimensional structure of the protein makes it prone to change in temperature, pH, chemicals, and more.
The shape of the active site changes
are theses right now I just need to explain them!

"..and more". I suspect your teacher wants something more specific. You did not mention concentration, both of the enzyme, and substrate. Those factors are very dominate in influence.

I will be happy to critique your thinking on three of these factors.

Sure, here are three different factors that influence the rate of enzyme activity and an explanation of each factor's influence:

1. Temperature: Enzymes have an optimal temperature at which they catalyze reactions most efficiently. As temperature increases, the kinetic energy of the molecules also increases, which enhances the rate of molecular collisions. This can lead to an increase in enzyme activity. However, if the temperature exceeds the optimum range for the specific enzyme, the increased kinetic energy can cause the enzyme to denature, leading to a loss of activity.

2. pH: Enzymes are sensitive to changes in pH because the concentration of hydrogen ions (H+) affects the charges on amino acid residues in the protein structure. Each enzyme has an optimal pH range at which it functions best. Deviating from this optimum can disrupt the structure and charge distribution within the enzyme molecule, altering the shape of the active site. This, in turn, affects the enzyme-substrate interaction and can either decrease or completely inhibit enzyme activity.

3. Substrate concentration: The rate of enzyme activity largely depends on the availability of substrate molecules. At low substrate concentrations, the enzyme molecules may not be fully occupied with substrates, resulting in a lower rate of reaction. As the substrate concentration increases, the number of collisions between the enzyme and substrate also increases, leading to a proportional increase in the rate of enzyme activity. However, there is a point where the active sites of the enzymes become saturated with substrate molecules, causing the rate of reaction to plateau, regardless of the excess substrate concentration.

It's important to note that there are other factors that can influence enzyme activity as well, such as the presence of inhibitors or activators, the concentration of cofactors or coenzymes, and the presence of competitive or non-competitive binding sites. However, the factors mentioned above are commonly studied and have a significant impact on enzyme activity.
