Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin. Acetylcholine, gastrin, and histamine stimulate the proton pump in parietal cells to release hydrogen ions and decrease pH.

Biology is the study of living organisms. Biotechnology involves
creating solutions to problems using living organisms. It's more like
how mechanical engineering uses machines to solve problems or how
computer engineering uses computers to solve problems.
The problems that biotechnology works to solve can range from medical
treatments (like stem cells) to advancements in agriculture (disease or
drought resistant plants, food with higher nutritional value) to
industrial processes (bacteria developed to replace toxic compounds used
to make paper, bacteria and algae that produce biofuels).
