How do enzymes affect chemical reaction?

Answer 1

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.

Answer 2

Enzymes increase the rate of chemical reactions by lowering the activation energy required for the reaction to occur. They do this by providing an alternative reaction pathway that requires less energy, making the reaction more likely to happen. Enzymes themselves are not changed or consumed in the reaction.

Answer 3

Enzymes are shaped proteins, normally produced by organisms to catalyse chemical reactions. They function in a similar way to chemical catalysts, by lowering (or occasionally raising) the 'activation energy' for a specific reaction, and are not used as a reactant. oweing to the nature of enzymes, as proteins, they function optimally at a set temperature and pH, as their presence outside these conditions is often to the detriment of the protein structure, or instead, in the case of low temperatures, slows the reaction and frequently fails to meet the activation energy. Enzymes will usually speed up a chemical reaction, and will additionally facilitate it when it would otherwise not occur.

Answer 4

enzymes are biological catalysts that speed up the rate of reaction without being changed or used up

Answer 5

Enzymes act as catalysts in biochemical reactions.

Answer 6

Enzymes speed up a reaction by allowing the reaction to take place at lower temperatures.

Answer 7

It acts as a catalyst, speeding up a slower reaction or allowing a previously impossible reaction to occur.

Answer 8

An enzyme is basically a biological catalyst and will speed up a reaction

Answer 9

The reaction speeds up.
