Which term best describes a protein that speeds up chemical reactions in living things?
a. structural protein
b. enzyme
c. amino acid
d. transport protein?

b. enzyme is the correct answer.

Explanation:

The chemical reactions require a catalyst termed as an enzyme to speed up the reaction in living things.

The enzyme speeds up the chemical reactions by giving another reaction pathway of reducing its activation energy.

Enzymes improve the efficiency of chemical reactions.

Enzymes decrease the activation energy of the chemical reaction which is required for a reaction to start.

Thus (b) enzyme is the correct answer.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

answer; i believe the correct answer is (solid gold);
