(5 points) Gastric acid is produced by parietal cells in the stomach. Its secretion is a complex and relatively energetically expensive process that acidifies the stomach with HCl while maintaining a neutral cytosolic pH. (1) Explain the process of acidifying gastric fluid and the function of each of the five transporters in achieving the acidic pH of the stomach. (2) Define each transporter based on the information discussed in class.
