Verified step by step guidance

Understand the role of gastrin: Gastrin is a hormone produced by G cells in the stomach lining. Its primary function is to stimulate the secretion of gastric acid (hydrochloric acid) by the parietal cells in the stomach.

Review the effects of gastrin: Gastrin also plays a role in enhancing gastric motility, which refers to the movement of the stomach muscles to mix and propel its contents.

Identify the false statement: The statement 'Gastrin inhibits the production of hydrochloric acid in the stomach' contradicts the known function of gastrin, which is to stimulate, not inhibit, the production of gastric acid.

Compare the statements: Evaluate each statement about gastrin based on your understanding of its functions. The false statement should be the one that does not align with the established physiological role of gastrin.

Conclude the analysis: Based on the information, the false statement is the one suggesting that gastrin inhibits hydrochloric acid production, as this is contrary to its actual function of stimulating acid secretion.
