What is the anatomy of protein digestion?
Understand the Problem
The question is related to the anatomy of protein digestion, specifically detailing the process and functions of various components in the gastrointestinal tract.
Answer
Protein digestion: Stomach (HCl & pepsin) → Small intestine (enzymes) → Amino acids absorption.
Protein digestion begins in the stomach with HCl and pepsin breaking down proteins into peptides. In the small intestine, additional enzymes break peptides into amino acids, which are then absorbed into the bloodstream.
Answer for screen readers
Protein digestion begins in the stomach with HCl and pepsin breaking down proteins into peptides. In the small intestine, additional enzymes break peptides into amino acids, which are then absorbed into the bloodstream.
More Information
Proteins are first denatured by stomach acid (HCl), making them accessible to enzymes like pepsin for initial breakdown. The process completes in the small intestine with other enzymes from the pancreas.
Tips
Misunderstanding the role of enzymes at different stages is common. Remember, pepsin acts in the stomach, while additional enzymes work in the small intestine.
