Describe the primary function of carbohydrates in living organisms.

• Energy storage and structural materials

• Catalyzing reactions

• Storing genetic information

What is the difference between saturated and unsaturated fats?

• Saturated fats are liquid at room temperature, unsaturated fats are solid.

• Saturated fats have no double bonds; unsaturated fats have one or more double bonds.

• Saturated fats are healthier than unsaturated fats.

• Saturated fats have double bonds; unsaturated fats have no double bonds.

How does the structure of a phospholipid contribute to its function in cell membranes?

• It forms rigid structures for protection.

• It forms bilayers due to hydrophilic heads and hydrophobic tails.

• It provides energy storage.

• It serves as a carrier for oxygen.

Explain how the properties of R groups in amino acids influence protein structure and function.

• R groups make proteins rigid and inflexible during the primary structure

• R groups determine how the protein folds and interacts with other molecules

• R groups only affect the protein's ability to bind with water.

• R groups have no impact on protein function.

Describe how the arrangement of monomers in a polysaccharide affects its function, using starch and cellulose as examples.

• Both are always digestible and provide energy.

• Starch is for structural support, and cellulose is for energy storage.

• Starch's branched structure is suitable for energy storage, while cellulose's linear structure provides support.

• Both have identical functions despite structural differences.
