what ph of gastric juice is secreted when starchy carbohydrates are swallowed, and is the amount of gastric juice reduced in volume compared to the ingestion of animal proteins?

Homework Answers

Answer #1

Parietal cells contain an extensive secretory network (called canaliculi) from which the hydrochloric acid is secreted into the lumen of the stomach.

The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, a level maintained by the proton pump H+/K+ ATPase.

Gastric juice is made up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day.
