What are the environmental factors that affect enzyme action


Enzyme is really a biological catalyst whose action is influenced by the following factors:

Temperature the higher the temperature, the faster the frequency of collision as well as the enzyme action is elevated. Enzyme works inside a narrow number of temperature. As soon as there is a deviation within the narrow limit, the enzyme can also be denatured , and its functionality thereafter halted

PH: catalysts just like enzymes work inside close of range of Ph [hydrogen ion concentration]. The hydrogen ion concentration also affects enzyme exercise just as temperature. An enhance or decrease in pH halts the enzyme function.

Concentration: enzymes are typically needed in low concentration. The concentration with the enzyme also affects the rate reaction the higher the concentration, the faster the rate of reaction until it reaches the stage of saturation at which it can not longer.


Concentration of substrate the concentration of substrate increases the rate of reaction and promotes enzyme activity after it is high until the enzyme is saturated.

Presence of inhibitors: inhibition of enzyme is also competitive etitive and non-competitive. In every situation, the inhibitor interferes with enzyme workout as soon as supply in ample number to compete, or also alter of configuration of the receptor site for ones enzyme.

Physical characteristics of reacting substances: matter exists in 3 states: solid, liquid and gas. An enzymatic reaction rate is elevated as the substrate changes it region from solid, to liquid and then gas. This is since there is increase surface area accessible for reaction as well as the enzyme can successfully jobs on a substrate molecules.
