STAAR Review 1 Biomolecules

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 store long-term energy, form cell membranes, and act as signaling molecules.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What role do enzymes play in biochemical reactions?

Back

Enzymes act as catalysts that lower the activation energy required for reactions, speeding up the process.

Front

What are carbohydrates primarily used for in living organisms?

Back

Carbohydrates are primarily used for short-term energy storage and as structural components.

Front

What is the structure of a lipid?

Back

Lipids are composed of glycerol and fatty acids, forming structures like triglycerides and phospholipids.

Front

What is the function of nucleic acids?

Back

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

Front

How do proteins contribute to cellular functions?

Back

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

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 is the role of carbohydrates in plant structure?

Back

Carbohydrates, particularly cellulose, provide structural support in plant cell walls.
