LIFE SCIENCE

Detailed explanation-1: -Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers.

Detailed explanation-2: -Catabolism is where larger and more complex molecules are broken down into smaller and simpler molecules. In contrast to anabolism, this process yields energy (ATP) that can be utilized by cells. An example of catabolism is the breakdown of glycogen to glucose or protein to constituent amino acids.

Detailed explanation-3: -Monomers come together to form macromolecules which are polymers of their monomer subunits. These polymers are built from monomers through a process known as dehydration synthesis (1).
