One of the factors that affects enzyme activity is the pH. If there are small changes in the pH, the enzyme will denature and catalytic activity will be lost. More »

Factors that influence enzyme activity include substrate concentration, enzyme concentration, temperature, pH and the presence of any activators or inhibitors. Enzymes act as catalysts for biochemical activities. More » Science Biology

In general, the rates of enzyme-catalyzed reactions are faster as temperature increases and slower as temperatures decrease below an optimal temperature level. When temperature increases, more molecules have more kinetic... More »

An enzyme is a biological catalyst, but there are also inorganic catalysts. Enzymes are globular proteins synthesized within cells to catalyze specific chemical reactions. Inorganic catalysts are mineral ions or other sm... More »

An enzyme is a type of protein that is used by cells to speed up chemical reactions. It acts as a catalyst, which means it participates in and affects a reaction but is not itself altered by that reaction. More » Science Chemistry Organic Chemistry

Allosteric control occurs when a small regulatory molecule causes the inhibition or activation of an enzyme at an allosteric site rather than the active site (the region of the enzyme that binds to substrates, where cata... More » Science Chemistry Organic Chemistry
