Question

The process of lipid digestion begins even before you take your first bite of food. Just the smell of food can begin digestive juices flowing. The most common lipids found in foods are primarily in the form of triglycerides. These lipids are hydrolyzed during digestion to yield monoglycerides, glycerol, and free fatty acids.
Rank the events from taking a bite of food rich in lipids to triglycerides being released to cells.
"Take a bite of pizza" to "Lipids are transported throughout the body."

1) Products of fat digestion are packaged into micelles and transported to the enterocytes.
2) With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
3) Gastric lipase digests some triglycerides.
4) Mechanical digestion by chewing breaks food down.
5) Lipid ­digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
6) The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
7) Lingual lipase is secreted from the pancreas and breaks down triglycerides.
8) During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.

Answer 1

Answer:

The given statements have been rearranged in the following order to depict the flow of events that account for lipid digestion in the human body:

1. Mechanical digestion by chewing breaks food down.
2. During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.
3. Gastric lipase digests some triglycerides.
4. The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
5. Lipid ­digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
6. Lingual lipase is secreted from the pancreas and breaks down triglycerides.
7. With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
8. Products of fat digestion are packaged into micelles and transported to the enterocytes.

The process is started in the mouth. Action of the teeth physically breaks down the food and increases it surface area that allows for better access to it for the enzymes to carry out mechanical digestion. Gastric lipases are those in the stomach, most of the lipid digestion takes place in the small intestine with the help of enzymes secreted by the pancreas and the small intestine itself. After digestion, the final products are taken up by the lymphatic system.

Hope that answers the question, have a great day!
