Chapter 1 Macromolecules

Front

What is a macromolecule?

Back

A macromolecule is a large molecule composed of thousands of atoms, typically organized into complex structures. Examples include proteins, nucleic acids, carbohydrates, and lipids.

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 a polymer?

Back

A polymer is a large molecule made up of repeating subunits called monomers.

Front

What is a monomer?

Back

A monomer is a small, basic molecular unit that can join together with other monomers to form a polymer.

Front

How do carbohydrates function in living organisms?

Back

Carbohydrates provide energy, serve as structural components, and play roles in cell recognition.

Front

What is the primary function of proteins?

Back

Proteins serve as enzymes, structural components, transport molecules, and play roles in immune response.

Front

What are lipids and their functions?

Back

Lipids are hydrophobic molecules that store energy, form cell membranes, and act as signaling molecules.

Front

What are nucleic acids?

Back

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

Front

How do glucose molecules relate to starch?

Back

Starch is a polymer made up of repeating glucose units, serving as an energy storage molecule in plants.

Front

What is the relationship between amino acids and proteins?

Back

Amino acids are the building blocks of proteins; they combine in specific sequences to form polypeptides.
