Macromolecules

Front

What are macromolecules?

Back

Large, complex molecules that are essential for life, including carbohydrates, lipids, proteins, and nucleic acids.

Front

What is a carbohydrate?

Back

A macromolecule made up of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio, and serves as a primary energy source.

Front

What are the main types of macromolecules?

Back

Carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

To provide energy and support cellular structure.

Front

What is a lipid?

Back

A macromolecule that is hydrophobic and includes fats, oils, and cholesterol, primarily used for energy storage and cell membrane structure.

Front

What are proteins made of?

Back

Long chains of amino acids linked by peptide bonds.

Front

What is the role of nucleic acids?

Back

To store and transmit genetic information; examples include DNA and RNA.

Front

What is glucose?

Back

A simple sugar (monosaccharide) that is a primary energy source for cells and a building block for carbohydrates.

Front

What are fatty acids?

Back

Building blocks of lipids, consisting of long hydrocarbon chains with a carboxyl group at one end.

Front

What is the structure of a phospholipid?

Back

A lipid molecule with a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails', essential for cell membrane formation.
