Which of the following statements about acid secretion in the stomach is correct?
a) Acetylcholine, gastrin, histamine and somatostatin all directly influence the parietal cell to increase acid secretion.
b) One mechanism by which acetylcholine increases acid secretion by the parietal cell is by stimulating the release of gastrin from G-cells.
c) Histamine acts directly on the parietal cell to inhibit acid secretion.
d) Gastrin stimulates acid secretion by the parietal cell indirectly by inhibiting histamine release from the ECL cells.
e) Acetylcholine, gastrin, histamine, and somatostatin all influence gastric acid secretion as endocrine hormones.

please answer both
Which of the following statements is true? The H+/K+-ATPase (proton pump) generates ATP as hydrogen ions are pumped out of parietal cells. Parietal cells of the stomach produce and release hydrochloric and nitric acid. Parietal cells of the stomach exchange sodium for potassium in order to maintain homeostasis prior to stimulation. When a histamine receptor antagonist is presented to parietal cells, followed by histamine, the internal pH of the parietal cells increases dramatically. Figure 23.4 suggests that...
