Enzymes are biocatalysts, they accelerate the reaction rate.
Different individual enzymes operate by different mechanisms.
reactions in which enzymes are involved as catalysts.
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.
The chemicals which are involved in a reaction are called Reagents or Reactants
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
No, enzymes can also be involved in breakdown reactions. Enzymes can catalyze both synthesis (anabolic) and breakdown (catabolic) reactions in the body, depending on the specific enzymatic reaction and the needs of the cell or organism.
enzymes
They lower the activation energy needed to start a chemical reaction.
No. That is one of the definitions of an enzyme. It is NOT altered in the reaction.
enzymes are the chemicals which speed up allchemical reactions. these reactions also include digestion. they are proteins in nature.
Enzymes are involved in a variety of human functions, including digestion, respiration, metabolism, and immune response. They speed up chemical reactions in the body by lowering the activation energy required for a reaction to occur. Enzymes are essential for many biological processes to take place efficiently.
Altering the pH might cause the enzymes involved in a reaction to be denatured. When enzymes are denatured, they do not function properly and the rate of the reaction either slows down or completely stops.
