1. Temperature: Enzymes have an optimal temperature at which they function most efficiently. High temperatures can denature enzymes, while low temperatures can slow down their activity.
2. pH: Enzymes have an optimal pH at which they function best. Changes in pH can alter the shape of the enzyme and affect its ability to bind to substrates.
3. Substrate concentration: Enzyme activity is dependent on the concentration of substrates available for the enzyme to bind to. At low substrate concentrations, enzyme activity may be limited by the availability of substrates.
4. Enzyme concentration: The rate of enzyme activity is directly proportional to the concentration of enzymes present. Increasing enzyme concentration can increase the rate of reaction, up to a certain point.
5. Inhibitors: Inhibitors can bind to enzymes and prevent them from catalyzing reactions. Competitive inhibitors compete with substrates for binding sites, while non-competitive inhibitors bind to a different site on the enzyme and change its shape.
6. Activators: Activators can bind to enzymes and increase their activity. They can either increase the affinity of the enzyme for its substrate or stabilize the active conformation of the enzyme.
7. Co-factors and co-enzymes: Some enzymes require additional molecules, known as co-factors or co-enzymes, to function properly. These molecules can be inorganic ions or organic molecules that help the enzyme catalyze reactions.
8. Enzyme structure: The structure of an enzyme is crucial for its function. Changes in the enzyme's structure, such as mutations or denaturation, can affect its activity.
2. pH: Enzymes have an optimal pH at which they function best. Changes in pH can alter the shape of the enzyme and affect its ability to bind to substrates.

1. Temperature: Enzymes have an optimal temperature at which they exhibit maximum activity. Deviations from this optimum can lead to decreased activity or denaturation of the enzyme.
2. pH: Enzymes also have an optimal pH range at which they function properly. Extreme pH values can alter the ionization state of amino acids in the active site, affecting enzyme-substrate binding and catalysis.
3. Substrate Concentration: The rate of enzymatic reactions increases as the substrate concentration increases until a saturation point is reached, when all enzyme active sites are occupied with substrate.
4. Product Concentration: High product concentrations can inhibit enzyme activity by competing with the substrate for the active site or by altering the enzyme conformation.
5. Enzyme Concentration: The reaction rate increases linearly with enzyme concentration until a point where all substrate molecules are processed.
6. Cofactors and Coenzymes: Some enzymes require cofactors (inorganic ions) or coenzymes (organic molecules) to function. Deficiencies in cofactors or coenzymes can impair enzymatic activity.
7. Inhibitors: Inhibitors are molecules that bind to enzymes and reduce or abolish their activity. They can be competitive (competing with the substrate for the active site) or non-competitive (binding to other parts of the enzyme).
8. Activators: Activators are molecules that increase enzymatic activity by enhancing enzyme-substrate interactions or stabilizing the enzyme conformation.
9. Substrate Specificity: Enzymes are selective for specific substrates. The shape and functional groups of the substrate determine how well it binds to the active site and is processed by the enzyme.
10. Post-translational Modifications: Phosphorylation, glycosylation, and other modifications can affect enzyme activity by altering enzyme structure or stability.
