Question

How does protein in a peanut butter sandwich become protein that your body can use? Think about the digestive and absorptive process beginning with the first bite of that sandwich, until the amino acids enter the circulatory system. Focus your attention on the steps involved in protein digestion illustrated in the focus figure.

Rank in the correct order from the first bite to the amino acids entering the circulatory system.

Explanation:

Below is the correct step by step process in the digestion of protein from peanut butter sandwich.

1. Mechanical  digestion  in the mouth  breaks down  the food.

2. A bolus enters  the stomach.

3. Hydrochloric  acid denatures  proteins and  activates pepsinogen  to form pepsin.

4. Pepsin breaks  down proteins  into polypeptide strands.

5. Chyme travels  from the stomach  to the small intestine.

6. Enzymes from  the pancreas  are secreted  into the small  intestine.

7. Enzymes in the  small intestine  break down  polypeptide  strands  into mostly  tripeptides and  dipeptides.

8. Tripeptides and  dipeptides are  broken down  into single  amino acids that

enter the blood  and travel to the liver.

Answer 2

Food and liquid-taking organs that break them down into compounds the body can use for growth, energy, and tissue repair. The correct step-by-step technique for digesting protein from a peanut butter sandwich is outlined here.

What is the ranking order of the digestion process?

1. Food is broken down via mechanical digestion in the mouth.

2. A bolus is injected into the stomach.

3. Pepsinogen is activated by hydrochloric acid, which denatures proteins and forms pepsin.

4. Pepsin is a digestive enzyme that breaks down proteins into polypeptide strands.

5. From the stomach to the small intestine, chyme moves.

6. The pancreas secretes its enzymes into the small intestine.

7. Polypeptide strands are broken down by enzymes in the small intestine into primarily tripeptides and dipeptides.

8. Single amino acids are broken down from tripeptides and dipeptides, which enter the bloodstream and proceed to the liver.
