What is a nucleic acid?

Back

A nucleic acid is a macromolecule composed of nucleotide monomers, which include a sugar, a phosphate group, and a nitrogenous base. Examples include DNA and RNA.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that involves the formation of a bond between two monomers with the removal of a water molecule.

Front

What is the difference between DNA and RNA?

Back

The primary difference is that RNA contains uracil instead of thymine, which is found in DNA.

Front

What are monomers?

Back

Monomers are the basic building blocks of macromolecules. Examples include monosaccharides, fatty acids, amino acids, and nucleotides.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a weak attraction between a partial positive charge of a hydrogen atom in one molecule and a partial negative charge in another molecule.

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They serve as a primary energy source.

Front

What are proteins made of?

Back

Proteins are made of amino acids linked together by peptide bonds. They perform a variety of functions in the body, including catalyzing reactions and providing structure.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical reaction that involves the breaking down of a compound by the addition of water, often used to break down polymers into monomers.

Front

What are lipids?

Back

Lipids are a diverse group of hydrophobic molecules, including fats, oils, and phospholipids, that are important for energy storage and cell membrane structure.

Front

What is the role of enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in the body by lowering the activation energy required for the reaction.
