An enzyme is the biological catalyst that speeds up chemical reactions.
Enzymes speed up the rate of chemical reactions by lowering activation energy, and are not used up in the reaction.
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
Enzymes are biological catalysts. This means they speed up a chemical reaction, but are not broken down or changed by it. They lower the amount of energy required for a chemical reaction to tack place.
A catalyst speeds up the rate of reaction, and lower the activation energy needed.

A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).

No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.

A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
Catalysts are substances that speed up the rate of a reaction without changing itself. Biological catalysts are substances that speed up biological/metabolic reactions. One example of biological catalyst is enzyme.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
