BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis is the process of adding a catalyst to facilitate a reaction.

Detailed explanation-2: -Enzymes are biological catalysts. They are proteins that fold into particular conformations such that they can help speed up very particular chemical reactions.

Detailed explanation-3: -catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.

Detailed explanation-4: -A catalyst is a substance that causes a chemical reaction to happen in a different way than it would happen without that catalyst-for example, a catalyst could cause a reaction to happen at a faster rate, or at a lower temperature, than would be possible without the catalyst.

Detailed explanation-5: -The rate of a reaction can be increased by adding a suitable catalyst. A catalyst is a substance which increases the rate of a chemical reaction but it is not used up (remains chemically unchanged at the end). It provides an alternative reaction pathway of lower activation energy.
