by lowering the activation energy
to speed up a chemical reaction
No. There is no type of a catalyst that is consumed in a reaction.
Enzyme or catalyst
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
Enzymes are substances that increase the speed of a chemical reaction. 1. A substrate attaches to an enzyms's active site. 2. The enzyme reduces the activation energy of the reaction. 3. The enzyme is not changes by this reaction. That is how a Biology book explains it. I hope that helps you.
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
An enzyme generally lowers the activation energy necessary for a reaction to proceed. This in turn may cause more of the reactants to go to products.
An enzyme works to speed up chemical reactions in a living organism.
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .
speed up chemical reaction because of the lowered activation energy
Enzyme
