What are lipids?

Back

Lipids are biomolecules that include fats, oils, and waxes. They serve as energy storage, insulation, and cushioning for organs.

Front

What is the primary function of lipids in cells?

Back

The primary function of lipids is energy storage, as well as providing insulation and protection for organs.

Front

What biomolecule do enzymes belong to?

Back

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

Front

What organelle is responsible for photosynthesis in plant cells?

Back

The chloroplast is the organelle found in plant cells where photosynthesis occurs.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules made of carbon, hydrogen, and oxygen, primarily serving as a source of energy.

Front

What is the role of proteins in the cell?

Back

Proteins perform various functions in the cell, including catalyzing reactions, providing structure, and regulating processes.

Front

What are nucleic acids?

Back

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

Front

How do lipids help in insulation?

Back

Lipids, such as blubber in whales, provide insulation by trapping heat and reducing heat loss.

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 significance of the cell membrane?

Back

The cell membrane is a lipid bilayer that protects the cell and regulates what enters and exits.
