What is a biomolecule?

Back

A biomolecule is a large molecule that is essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What are the four main types of biomolecules?

Back

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

What is the primary function of proteins in the body?

Back

Proteins are essential for building and repairing tissues, making enzymes and hormones, and supporting immune function.

Front

What are lipids and their primary function?

Back

Lipids are a group of biomolecules that include fats, oils, and waxes, primarily serving as a source of long-term energy and forming cell membranes.

Front

What are carbohydrates and their role in the body?

Back

Carbohydrates are biomolecules that provide a primary source of energy for the body, found in foods like pasta, bread, and sugars.

Front

What are nucleic acids and their significance?

Back

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

Front

How do proteins differ from carbohydrates and lipids?

Back

Proteins are made of amino acids and are primarily involved in structure and function, while carbohydrates are made of sugars and provide energy, and lipids are made of fatty acids and provide long-term energy.

Front

What is the structure of a lipid?

Back

Lipids typically have a hydrophobic (water-repelling) structure, often consisting of long hydrocarbon chains or rings.

Front

What is the role of enzymes in relation to proteins?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

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, affecting their physical state at room temperature.
