AP Biology Unit 1 Review

Front

What are proteins and their functions in the cell?

Back

Proteins are macromolecules that serve various functions in the cell, including forming structural parts, acting as enzymes, and facilitating cell movement.

Front

What type of bond is formed between water molecules due to partial charges?

Back

A hydrogen bond is formed between water molecules due to the attraction of the partial negative charge of one water molecule to the partial positive charge of another.

Front

What is a false statement about carbon?

Back

Carbon cannot form polar covalent bonds with hydrogen; it forms nonpolar covalent bonds instead.

Front

What is hydrolysis and its role in digestion?

Back

Hydrolysis is a chemical process that involves breaking down complex molecules into simpler ones, such as the digestion of sucrose into glucose and fructose.

Front

Which biological macromolecule contains phosphorus?

Back

Nucleic acids, such as DNA and RNA, contain phosphorus in their structure.

Front

What are the four main types of macromolecules?

Back

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

Front

What is the primary function of nucleic acids?

Back

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

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates serve as a primary energy source and are involved in structural functions in cells.

Front

What is a peptide bond?

Back

A peptide bond is a covalent bond formed between two amino acids during protein synthesis.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms, while unsaturated fats contain one or more double bonds.
