Are enzymes affected by the chemical reaction?

Answer 1

No, enzymes are considered catalysts in a reaction. This means that they help a reaction occur that may not otherwise. By definition catalysts (and therefore enzymes) are NOT used up during a reaction. They assist the reactants and then are regenerated to be used again (whereas the reactants become new products are are consumed). They do this by lowering the activation energy (the energy needed to cause the reaction). They lower the activation energy by a variety of ways, usually by getting the involved reactants into a close proximity, and by causing a physical or chemical change to them, allowing the reaction to proceed.

In our bodies enzymes are essential as the body has a very specific environment (temperature, pH range, etc) that make several of our vital reaction impossibly slow without them to help us along. Without them, the reactions that must occur millions of times each second in our bodies could take weeks, months, or years to happen otherwise. At that scale, our life would be impossible.

Answer 2

yes enzymes are used in the breaking down of food particles. enzymes speed up or slow down chemical reactions.

Answer 3

No, basically enzymes remain unchanged at the end of any chemical reaction unless being affected by certain factors such as temperature or pH changes.....

Answer 4

enzymes work as catalyst in a chemical reaction.

Answer 5

No they are the catalyst of the reaction, of course they do take part in the reaction without loosing ruining its ability to go for another reaction.

Answer 6

Enzymes are catalysts.
