Macromolecules

What is the primary function of carbohydrates in living organisms?

• To provide energy.

• To store genetic information.

• To act as enzymes.

• To transport oxygen in the blood.

How do carbohydrates differ from lipids in terms of structure?

• Carbohydrates are made of amino acids, while lipids are made of glycerol and fatty acids chains.

• Carbohydrates are made of saccharide rings, while lipids are made of glycerol and fatty acids chains.

• Carbohydrates are made of nucleotides, while lipids are made of glycerol and fatty acids chains.

• Carbohydrates are made of simple sugars, while lipids are made of complex proteins.

What are the building blocks of proteins?

• Nucleotides

• Fatty acids

• Amino acids

What is the structure of a phospholipid?

• A phospholipid has a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

• A phospholipid consists of three hydrophilic heads and one hydrophobic tail.

• A phospholipid is made up of two hydrophobic heads and one hydrophilic tail.

• A phospholipid has a single hydrophilic tail and a double hydrophobic head.

What is the difference between saturated and unsaturated fats?

• Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.

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

• Saturated fats contain more calories than unsaturated fats.

• Saturated fats are healthier than unsaturated fats.
