Back

Lipids are primarily used by bears during hibernation to provide energy.

Front

What is the structure of a lipid?

Back

Lipids typically consist of long hydrocarbon chains or rings, which can be saturated or unsaturated.

Front

How do carbohydrates function in living organisms?

Back

Carbohydrates serve as a primary source of energy and are involved in structural functions in 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.

Front

What is the role of proteins in biological processes?

Back

Proteins serve as enzymes, structural components, and play roles in transport and signaling within cells.
