Back

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

Front

What is the primary function of carbohydrates?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What are lipids and their main functions?

Back

Lipids are biomolecules that include fats, oils, and waxes. They provide energy storage, insulation, and are key components of cell membranes.

Front

What are proteins made of?

Back

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

Front

What is the role of nucleic acids?

Back

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

Front

What are triglycerides?

Back

Triglycerides are a type of lipid that consists of three fatty acids attached to a glycerol molecule, serving as a major form of energy storage.

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, making them liquid at room temperature.

Front

What are examples of carbohydrates?

Back

Examples of carbohydrates include sugars (like glucose), starches (like pasta and bread), and fibers.

Front

What is the structure of a protein?

Back

Proteins have a complex structure that includes primary (amino acid sequence), secondary (alpha helices and beta sheets), tertiary (3D shape), and quaternary (multiple polypeptide chains) levels.
