Which of the following would most likely happen if the stomach decreased the amount of gastric juices secreted?
a. enzyme production would decrease
b. the food leaving the stomach would digest through mechanical digestion
c. stomach ph would increase resulting in acid reflux
d. the stomach would churn and break down the food

B

Explanation:

The stomach digests food both chemically and mechanically. Food is churned in the stomach to break it into smaller pieces. This is mechanical digestion. Secreted Gastric Juices which comprise pepsinogen, amylases, HCL, and lipases hydrolyze bigger molecules of the food into simpler molecules.  If the gastric juices were not adequately secreted then most digestion would be mechanical rather than chemical.
