AP Biology: Unit 1 Review

Front

What is the main difference between DNA and RNA?

Back

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

Front

What is hydrolysis?

Back

Hydrolysis is the process of breaking a bond in a polymer using water, resulting in the separation of monomers.

Front

What type of protein structure is formed by R group bonding?

Back

Tertiary structure is formed by R group bonding, which determines the protein's three-dimensional shape.

Front

What gives polypeptides their unique characteristics?

Back

The R groups (side chains) of the amino acids in the polypeptide chain give it unique characteristics.

Front

What is NOT a result of hydrogen bonding in water?

Back

Dissolving fats is not a result of hydrogen bonding in water; cohesion, adhesion, and surface tension are.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is the process of joining two molecules by removing water, forming a bond.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the sequence of amino acids in a polypeptide chain.

Front

What role do enzymes play in biological reactions?

Back

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

Front

What is the function of the phosphate group in nucleotides?

Back

The phosphate group in nucleotides is essential for forming the backbone of DNA and RNA.
