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 »

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 »

A high fever can cause a denaturation, or change in shape, of an enzyme, resulting in less activity for the enzyme to catalyze reactions in the body, according to the BBC. When there is elevated temperature in the body, ... More »

The factors that affect catalase activity are temperature, pH level and the concentration of the substrate. If any of these three factors are changed, the effectiveness of catalase to catalyze the decomposition of hydrog... 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 »

Physical activity increases body temperature; increased body temperature raises metabolism. A person who is exercising burns more energy (or calories) than someone sitting at a desk. More »
