is to catalyse or increase the rate of reaction without any change in itself .
Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are highly specific and can catalyze a wide range of reactions within cells.
The primary function of an enzyme or any biological catalyst is to increase the rate of a chemical reaction by lowering the activation energy barrier, thereby facilitating the conversion of substrate molecules into products. This process allows cells to efficiently carry out metabolic reactions necessary for growth, maintenance, and energy production.
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
The enzyme activity curve shows that as enzyme concentration increases, the reaction rate also increases. However, there is a point where adding more enzyme does not further increase the reaction rate, indicating that there is a limit to the effect of enzyme concentration on reaction rate.
An enzymatic reaction is an equilibrium reaction and the determiners of rate include enzyme and substrate concentration. An increase in either enzyme or substrate concentration will increase the rate of the reaction until one or the other component becomes saturated, beyond its ability to react or be reacted at a higher rate.
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.

The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
The condition that will NOT increase the reaction rate of an enzyme is a decrease in temperature. While moderate increases in temperature can enhance reaction rates by increasing molecular movement, a decrease in temperature typically slows down enzyme activity and substrate interactions. Other factors like optimal pH, substrate concentration, and enzyme concentration tend to positively influence reaction rates.
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
