Front

What macromolecule(s) contain nitrogen?

Back

Nucleic Acids and Proteins.

Front

What are the components of a protein monomer?

Back

Amine Group, R Group, Carboxyl Group (NOT Nitrogenous Base).

Front

What are the components of a nucleic acid monomer?

Back

Pentose sugar, nitrogenous base, phosphate (NOT amino acid).

Front

Why is water considered a polar molecule?

Back

Due to polar covalent bonds in its structure.

Front

What is a key difference between DNA and RNA?

Back

They differ in sugar type, nitrogenous bases, and strandedness (NOT phosphate group).

Front

Define macromolecule.

Back

Large, complex molecules essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What is the function of proteins in biological systems?

Back

Proteins serve as enzymes, structural components, signaling molecules, and transporters.

Front

What is the role of nucleic acids?

Back

Nucleic acids store and transmit genetic information (DNA and RNA).

Front

What is a polar covalent bond?

Back

A type of bond where electrons are shared unequally between atoms, leading to partial charges.

Front

What are the four main types of macromolecules?

Back

Proteins, Nucleic Acids, Carbohydrates, and Lipids.
