Lipid Digestion REVIEW

What is the role of bile in lipid digestion?

• Emulsification of large lipid droplets

• Transporting oxygen in the blood

• Regulating body temperature

• Breaking down carbohydrates

How does bile help in the emulsification of lipids?

• By reducing the acidity of lipids

• By increasing the size of lipids

• By converting lipids into carbohydrates

• By breaking down lipids into smaller droplets

Name two enzymes involved in lipid digestion.

• Lactase and sucrase

• Amylase and protease

• Lipase and phospholipase

• Pepsin and trypsin

What is the function of lipase in lipid digestion?

• Breaking down lipids into fatty acids and glycerol

• Converting fatty acids into lipids

• Aiding in protein digestion

• Breaking down carbohydrates into glucose

How are digested lipids absorbed in the small intestine?

• Absorbed as fatty acids and monoglycerides

• Absorbed as glucose and fructose

• Absorbed as amino acids

• Absorbed as cellulose and starch

Explain the process of micelle formation in the absorption of digested lipids.

• The process involves the use of carbohydrates to surround the lipid molecules

• Bile salts and phospholipids surround the hydrophobic lipid molecules

• Micelles are formed by the aggregation of proteins

• Lipids are broken down into fatty acids and glycerol

Where does lipid digestion primarily occur in the small intestine?

• Large intestine

• Small intestine

• Stomach

• Esophagus

Describe the role of the intestinal cells in the absorption of digested lipids.

• Intestinal cells produce and secrete enzymes and bile salts, and then reabsorb the digested lipids into the bloodstream.

• Intestinal cells have no role in the absorption of digested lipids

• Intestinal cells break down carbohydrates instead of absorbing lipids

• Intestinal cells excrete digested lipids out of the body

What is the overall process of lipid metabolism in the body?

• Lipid metabolism involves the processes of digestion, absorption, transportation, storage, and utilization of lipids in the body.

• Lipid metabolism involves the processes of bone formation and muscle contraction in the body.

• Lipid metabolism involves the processes of photosynthesis and respiration in the body.

• Lipid metabolism involves the processes of protein synthesis and cell division in the body.

What is chyme?

• A mixture of saliva and gastric juices

• A watery solution of digested food in the stomach

• A substance produced by the liver

• A type of enzyme that breaks down lipids
