Answer to the question
Answers
Answer:
HCl is one of the gastric juices secreted by stomach. HCl converts the inactive enzyme pepsinogen into its active form pepsin. Pepsin digests proteins and breaks them into amino acids. HCl also kills harmful pathogens or particles in our food when it reaches the stomach through the gastrointestinal duct.
Digestive enzymes are substances produced by our bodies that help us to digest the foods we eat. These enzymes are secreted by the various parts of our digestive system and they help to break down food components such as proteins, carbohydrates, and fats.
