Question

In what tubes did digestion not occur? explain why in each case. egg white pepsin

Answer 1

In the human digestive system, particularly in the Esophagus digestion can not occur.

Esophagus, is a muscle tube that transports the unfinished meal from the mouth to the stomach for further absorption. As a result, the esophagus is one area of the digestive tract where digestion is not completed.

- Tube 1: HCl breaks down salivary amylase

- Tube 2: no digestive enzyme, no bile

- Tube 3: no pancreatic enzymes

- Tube 4: boiling denatures salivary amylase and absence of Pepsin.

Egg digestion occurs in the small intestine not in the Esophagus.

Pepsin digests egg white.

• Pepsin is a peptidase, a special enzyme with the function to degrade proteins into amino acids. Like all enzymes, pepsin is also a protein.
• The small intestine, where the majority of protein digestion takes place, receives the chyme from the stomach that contains the broken-down egg particles. More enzymes are present in the digestive juice the pancreas secretes, which further breaks down the protein fragments.
