Front

What is dehydration synthesis?

Back

Dehydration synthesis is the process of forming a bond between monomers by removing a water molecule.

Front

What is the main difference between DNA and RNA?

Back

The main differences between DNA and RNA include the type of sugar, nitrogenous bases, and strandedness. The phosphate group is the same in both.

Front

What component of a polypeptide forms a peptide bond with the next amino acid?

Back

The carboxyl group of one amino acid forms a peptide bond with the amino group of another.

Front

What are the results of hydrogen bonding in water molecules?

Back

Hydrogen bonding in water molecules results in cohesion, adhesion, and surface tension.

Front

Why is water considered a polar molecule?

Back

Water is considered polar due to the presence of polar covalent bonds between oxygen and hydrogen atoms.

Front

Define hydrolysis.

Back

Hydrolysis is the chemical process of breaking down a compound by adding water.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up biological reactions by lowering the activation energy.

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the significance of the R group in amino acids?

Back

The R group determines the properties and identity of each amino acid, influencing protein structure and function.
