Why are enzymes known as biocatalysts? enzymes act as catalysts that modify themselves to increase the rate of chemical reaction. enzymes act as catalysts that remain unmodified as they increase the rate of a chemical reaction. enzymes act as catalysts that remain unmodified as they increase the temperature of a chemical reaction.

 Enzymes act as catalysts that remain unmodified as they increase the rate of a chemical reaction.

Explanation:  Enzymes are known as biocatalysts because they are the substances which are just used to increase the rate of the reaction by decreasing the activation energy.

The catalyst does not alter the temperature neither they modify themselves, they just change the path of the reaction which can increase the rate of the reaction.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
