1. Lipids: high energy value storage material

2. Carbohydrates: primary source of energy for most organisms

3. Proteins: some types lower the energy of activation for reactions

4. Nucleic acids: used primarily for protein synthesis

Explanation:

Energy is stored in an organisms body for longer period of times as fats. Fats are lipid molecules. Hence, lipids are high energy value storage material.

Carbohydrates are the quickest source of energy for organisms and they can be broken down easily. Hence, carbohydrates are the primary source of energy for most organisms.

Enzymes are proteins which speed up a reaction and lower the activation energy for reactions.

Nucleic acids of the DNA are used to make mRNA which makes proteins. Hence, nucleic acids are used primarily for protein synthesis.
