Identify the incorrect statement:

1. Increasing acidity in the stomach stimulates endocrine cells in the gastric epithelium to produce somatostatin that inhibits further HCl secretion

2. HCl production increases in response to carbohydrates entering the stomach

3. HCl secretion is inhibited when acidity increases in the small intestine

4. Gastrin, histamine, and acetylcholine all act to increase HCl secretion
