PATHOLOGY

Detailed explanation-1: -Nucleic acids do not provide the bulk energy for an organism, so they are not nutrients.

Detailed explanation-2: -Energy is either released or transferred as molecules are broken down into smaller molecules. All of the leftover atoms from the breakdown of biomolecules are recycled and used by the body. All of the energy produced by breaking down biomolecules is used to do work in the cell.

Detailed explanation-3: -Polymers are broken down into monomers through a process called hydrolysis (hydro = water, lyse = to break). Biologically important molecules are grouped into four classes: carbohydrates, lipids, proteins, and nucleic acids. Polymers are large molecules made up of smaller molecules, referred to as monomers.

Detailed explanation-4: -Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism’s genetic code-the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth.
