Front

What are biomolecules?

Back

Biomolecules are organic molecules that are essential for life, including carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of lipids?

Back

Lipids primarily function as long-term energy storage, insulation, and making up cell membranes.

Front

What is the difference between polar and non-polar molecules?

Back

Polar molecules have a partial charge due to unequal sharing of electrons, while non-polar molecules have no charge and share electrons equally.

Front

Why do lipids not mix with water?

Back

Lipids are non-polar and hydrophobic, meaning they do not interact well with polar substances like water.

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates provide short-term energy and serve as structural components in cells.

Front

What polysaccharide do plants use for energy storage?

Back

Plants use starch as a polysaccharide to store energy.

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides structural support and protection to plant cells.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and organelles, such as plant and animal cells.

Front

What is the function of proteins in cells?

Back

Proteins perform a variety of functions including catalyzing biochemical reactions, providing structure, and facilitating communication.

Front

What are nucleic acids and their role?

Back

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