Oligodendrocytes is located in the central nervous system. It is a type of neuroglia (group of cells that support neurons). Its function is to produce myelin sheaths around CNS nerve fibers. Oligodendrocytes are types of cells that make up the supportive or glial tissue of the brain.ligodendrocytes are found in the central nervous system, primarily in the brain but also in smaller numbers in the spinal cord. Oligodendrocytes are small, rounded cells with one or a few processes, or extensions.
Activation of pepsinogen in the stomach. The peptidase in the stomach is pepsin. Pepsin works optimally in the acidic environment of the stomach, being active at pH 2-3, but becoming inactivated when the pH is above 5. The chief cells at the base of the gastric glands secrete the zymogen, which is called pepsinogen.Activation of pepsinogen starts when hydrocholoric acid (HCl) , which is secreted by the parietal cells partially activates pepsinogen (pepsinogen* in figure).This partially active enzyme then cleaves the peptide from other pepsinogen molecules to form active pepsin.he chief cells at the base of the gastric glands secrete the zymogen, which is called pepsinogen. Activation of pepsinogen starts when hydrocholoric acid (HCl) , which is secreted by the parietal cells partially activates pepsinogen (pepsinogen* in figure).
