WebThe regulated secretory pathway is used for proteins that are stored and secreted on demand. For example, insulin is produced by the beta cells of the pancreas and stored in dense core secretory granules. When blood sugar increases to a threshold level, insulin containing secretory granules fuse with the plasma membrane, releasing insulin to the … WebFeb 1, 2004 · Proteins of the secretory pathway can be attached to membrane structures by various mechanisms.
