Macromolecules!

What are lipids and their main function?

• Lipids are proteins that help in digestion.

• Lipids are carbohydrates that provide quick energy.

• Lipids, or fats, are macromolecules that store energy, provide insulation, and make up cell membranes.

• Lipids are vitamins that support immune function.

How are macromolecules related to nutrition?

• Macromolecules are essential nutrients that provide energy, support growth, and maintain bodily functions.

• Macromolecules are only important for energy production and have no role in growth.

• Macromolecules are harmful substances that should be avoided in a healthy diet.

• Macromolecules are vitamins that help in the absorption of minerals.

What is the role of proteins in the body?

• Proteins are primarily used for energy production.

• Proteins are essential for building and repairing tissues, as well as for making enzymes and hormones.

• Proteins are mainly responsible for storing genetic information.

• Proteins help in the absorption of vitamins and minerals.

How do carbohydrates provide energy?

• Carbohydrates are stored as fat for later use.

• Carbohydrates are broken down into glucose, which is used by cells for energy.

• Carbohydrates are converted into proteins for muscle repair.

• Carbohydrates are eliminated from the body as waste.

How do enzymes function as proteins?

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

• Enzymes are proteins that provide structural support to cells.

• Enzymes are proteins that transport oxygen in the blood.

• Enzymes are proteins that store energy for the body.

What are nucleic acids and their function?

• Nucleic acids are proteins that catalyze biochemical reactions.

• Nucleic acids, such as DNA and RNA, store and transmit genetic information.

• Nucleic acids are lipids that provide energy to cells.

• Nucleic acids are carbohydrates that serve as structural components.

What is a polymer?

• A small molecule that cannot be broken down further.

• A large molecule made up of repeating subunits called monomers.

• A type of chemical reaction that forms new compounds.

• A mixture of different types of plastics.

What is the caloric value of lipids compared to carbohydrates?

• Lipids provide about 4 calories per gram, while carbohydrates provide about 9 calories per gram.

• Lipids provide about 7 calories per gram, while carbohydrates provide about 4 calories per gram.

• Lipids provide about 9 calories per gram, while carbohydrates provide about 4 calories per gram.

• Lipids provide about 5 calories per gram, while carbohydrates provide about 3 calories per gram.

What is the primary function of carbohydrates?

• To provide structural support to cells.

• To serve as a source of energy for the body.

• To facilitate the absorption of nutrients.

• To act as a catalyst in biochemical reactions.

What is the difference between saturated and unsaturated fats?

• Saturated fats have one or more double bonds between carbon atoms.

• Unsaturated fats have no double bonds between carbon atoms.

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

• Both saturated and unsaturated fats are identical in structure.
