Question

A protein that speeds up a specific chemical reaction without undergoing changes itself is called

Answer 1

Biocatalyst

Step-by-step explanation:

The metabolism or a chemical reaction is a characteristic feature of the living organisms to survive. The biological chemical reactions involve the formation of bond and bombarding of element atoms so takes time and becomes slow.

The living organism formed the protein molecules which could speed up the reactions called a catalyst.

The catalyst is the tertiary globular structures of proteins which possess a pore called active site to which the substrate binds temporarily as well as lowers the activation energy of the chemical reaction.

Thus, Biocatalyst is the correct answer.

Answer 2

Enzyme

Step-by-step explanation:

Some proteins have the ability to speed up the rate of chemical reactions. These proteins are called enzymes. Enzymes lower down the required activation energy for the reaction to occur. In this way, the presence of enzymes allows the reactions to occur at a fast rate even at lower temperatures. The enzymes are not consumed during the chemical reactions. Completion of one round of a reaction releases the products from the enzymes and enzymes become available for the next round of the reaction.
