Front

What are macromolecules?

Back

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

Front

What are the four main types of macromolecules?

Back

Carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

To provide energy and structural support in cells.

Front

What are lipids and their main functions?

Back

Lipids are fats, oils, and cholesterol that store energy, provide insulation, and make up cell membranes.

Front

What are proteins made of?

Back

Proteins are made of amino acids linked together by peptide bonds.

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.

Front

What is lactase and what does it do?

Back

Lactase is an enzyme that breaks down lactose into monosaccharides.

Front

Why do enzymes function best at specific temperatures?

Back

Enzymes have optimal temperature ranges where their structure and activity are maximized.

Front

What are nucleic acids and their functions?

Back

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

Front

What is the difference between saturated and unsaturated fats?

Back

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