Question

question 28 (2 points) key characteristics of the stomach as a digestive organ include neutral ph, primary site of food chemical digestion alkaline ph, site of a large amount of food absorption into circulation acidic ph, site of a large amount of food absorption into circulation alkaline ph, site of mechanical digestion of food acidic ph, begins protein digestion

Explanation:

The stomach secretes gastric acid, resulting in an acidic pH environment. It is where protein - digestion begins as pepsin (an enzyme for protein digestion) is activated in an acidic medium. Most food absorption occurs in the small intestine, not the stomach. Mechanical digestion also occurs in the mouth (chewing) and stomach (churning), but the key characteristic related to its digestive function is the acidic pH for protein digestion start.

Answer:

E. acidic pH, begins protein digestion
