Answer:
<em>The process of </em><u><em>exocytosis </em></u><em>could be responsible for its secretion. </em>
Explanation:
Exocytosis can be described as a process in which molecules are transported out of a cell in vesicles. The process of exocytosis usually requires energy as molecules are moved out of a cell by the method of active transport.
As certain cells that line the stomach secrete a protein and release it into the stomach we can infer that the process is exocytosis. Peptides, hormones and various antibodies are also transported to different locations through the process of exocytosis.
