Front

What is the main difference between DNA and RNA?

Back

DNA contains deoxyribose sugar, while RNA contains ribose sugar. DNA is double-stranded, whereas RNA is single-stranded.

Front

What is the role of the carboxyl group in amino acids?

Back

The carboxyl group (-COOH) is involved in forming peptide bonds between amino acids during protein synthesis.

Front

Which macromolecules contain nitrogen?

Back

Proteins and nucleic acids (DNA and RNA) contain nitrogen.

Front

What is dehydration synthesis?

Back

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

Front

How do phospholipids orient in a cell membrane?

Back

Phospholipids orient in a bilayer with hydrophilic (water-attracting) heads facing the exterior and hydrophobic (water-repelling) tails facing inward.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is the function of nucleic acids?

Back

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

Front

What is the difference between hydrolysis and dehydration synthesis?

Back

Hydrolysis is the process of breaking down polymers into monomers by adding water, while dehydration synthesis is the process of forming polymers by removing water.

Front

What are the four main types of macromolecules?

Back

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

Front

What is the primary function of carbohydrates?

Back

Carbohydrates serve as a primary energy source and structural components in cells.
