This is secreted by the oxyntic cells (parietal cells.) The secretion of HCI stops when energy conversion is blocked by DNP, etc. It probably acts as a mild antiseptic against swallowed bacteria. The secretory reactions proceed in three stages: (a) One ∼P combines with reduced low-energy precursor to produce a reduced high-energy precursor. Pepsin is inactive in neutral or alkaline medium, but it is highly proteolytic in strong acid solutions. Welcome to BiologyDiscussion!
