what are the three factors that affect enzyme activity?
11797
Factors affecting enzyme activity Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

Three factors can affect the enthalpy of reaction: The concentrations of the reactants and the products. The temperature of the system. The partial pressures of the gases involved (if any)

Enzymes are important in living organisms because they speed up chemical reactions that take place in cells. ... Some factors that can affect enzyme activity are excessive temperature and extreme pH. These factors change the enzyme's shape and make it nonfunctional.

Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%. ... Over a period of time, enzymes will be deactivated at even moderate temperatures.

Because most enzyme reactions are reversible, an enzyme can synthesize and decompose molecules. Enzymes reaction rate is dependable on several factors: pH, temperature, and concentration of both the enzyme and substrate.

An enzyme is a protein that catalyzes (increases the rate of) chemical reactions. The optimal temperature of most enzymes, or the temperature at which enzymes best facilitate reactions, is between 35 and 40 degrees Celsius.
928759
Enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH. ... Extremely high or low pH values generally result in complete loss of activity for most enzymes. pH is also a factor in the stability of enzymes.

Enzymes are catalysts, so they affect activation energy by decreasing the required amount of activation energy allowing chemical reactions to occur or speed up. It does not affect the amount of energy that is released by the reaction.

As the temperature is increased enzyme activity increases to a maximum value at the optimum temperature (around 37 oC for most human enzymes).

Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
