What is the role of proteins in the structure of cells and tissues?

• Proteins have no role in the structure of cells and tissues.

• Proteins are responsible for the production of energy in cells and tissues.

• Proteins provide structural support to cells and tissues.

• Proteins are only found in the extracellular matrix of cells and tissues.

What are the two main types of enzymes?

• Intracellular enzymes and extracellular enzymes

• Catabolic enzymes and anabolic enzymes

• Metabolic enzymes and digestive enzymes

• Protein enzymes and carbohydrate enzymes

What are the functions of carbohydrates in the body?

• Carbohydrates are harmful to the body and should be avoided.

• Carbohydrates have no function in the body.

• Carbohydrates are only used for energy storage in the body.

• Carbohydrates serve as the primary source of energy for the body and also play a role in cell signaling, immune function, and the structure of DNA and RNA.

What are the different types of carbohydrates based on their molecular structure?

• Starch, Cellulose, Glycogen

• Simple carbohydrates, Complex carbohydrates, Fiber

• Glucose, Fructose, Sucrose

• Monosaccharides, Disaccharides, Polysaccharides

What is the primary function of lipids in the body?

• Transport of oxygen, nutrients, and waste products

• Regulation of body temperature

• Source of energy, insulation, and protection

• Building and repairing tissues

How do lipids contribute to energy storage in the body?

• Lipids are stored in the muscles for energy storage

• Lipids are converted into and stored as adipose tissue, which can be broken down and converted back into energy when needed.

• Lipids are broken down into glucose for energy storage

• Lipids are converted into proteins for energy storage
