AP Biology Unit 1 Review

Front

What are the components that characterize RNA?

Back

RNA is characterized by a phosphate group, ribose sugar, and uracil as its nitrogenous base.

Front

What roles do proteins play in the cell?

Back

Proteins can form structural parts of the cell, act as enzymes, and be involved in cell movement.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical process that involves the breakdown of a compound by the addition of water, such as the digestion of sucrose into glucose and fructose.

Front

What is a false statement regarding carbon?

Back

Carbon has the capacity to form polar covalent bonds with hydrogen (this statement is false; carbon typically forms nonpolar covalent bonds with hydrogen).

Front

What is denaturation in proteins?

Back

Denaturation is the process by which a protein loses its native conformation and functionality due to factors like heat or pH changes.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.

Front

What is the function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

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 dehydration synthesis?

Back

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

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.
