AP Biology Unit 1 Review

Front

What macromolecule makes up the cell membrane's lining?

Back

Phospholipids are the primary macromolecules that form the cell membrane, consisting of hydrophilic heads and hydrophobic tails.

Front

What is a saturated fatty acid?

Back

A saturated fatty acid is a type of fatty acid that has no double bonds between carbon atoms, resulting in a straight chain structure.

Front

What are the monomers of nucleic acids?

Back

The monomers of nucleic acids are nucleotides, which consist of a pentose sugar, a nitrogenous base, and a phosphate group.

Front

What is tertiary structure in proteins?

Back

Tertiary structure refers to the overall three-dimensional shape of a protein, formed by R group interactions and bonding.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is the attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is the role of phospholipids in the cell membrane?

Back

Phospholipids create a bilayer that serves as a barrier to protect the cell and regulate the movement of substances in and out.

Front

What is the difference between saturated and unsaturated fatty acids?

Back

Saturated fatty acids have no double bonds and are solid at room temperature, while unsaturated fatty acids have one or more double bonds and are liquid.

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 primary structure of a protein?

Back

The primary structure of a protein is the 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.
