How do enzyme act as a catalyst?

Answer 1

They lower the activation energy of catalytic reactions. I think I remember a few ways they do this. One: they can provide a safe haven for two substrates to interact. Two: They can actually stress the bonds of a substrate causing the reaction by new bonds forming. Three: These enzyme proteins, like all proteins. are amino acids with R groups. Some enzymes can catalyze a reaction with the R group.

Answer 2

In over simplistic terms, cellular metabolism (reactions in the cell ie. photosynthesis in plants) need to occur quickly, or the organism wouldn't survive.

Answer 4

Enzymes act as catalysts by lowering the activation energy needed for a chemical reaction to occur. They do this by binding to the reactants and stabilizing the transition state, making it easier for the reaction to proceed. Once the reaction is complete, enzymes release the products and are available to catalyze more reactions.

Answer 5

A catalyst is a substance that facilitates chemical reactions without itself changing. Enzymes act as catalysts in the processes of food digestion and DNA synthesis.

Answer 7

Enzymes are protein catalysts and therefore are biological molecules that perform enzymatic reactions.
