Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the four macromolecules?
A
proteins, nucleic acids, carbohydrates, and lipids
B
monosaccharides, lipids, polysaccaharides, and proteins
C
RNA, DNA, proteins, and carbohydrates
D
proteins, DNA, RNA, and steroids
Explanation: 

Detailed explanation-1: -Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules-large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

Detailed explanation-2: -11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits.

Detailed explanation-3: -There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass.

Detailed explanation-4: -Proteins-Molecular Machines. Nucleic Acids-Information Repositories. Lipids-Waterproof Membranes. Carbohydrates-Stored Energy.
