no,pepsin does not acts in the absence of hydrochloric acid
Protein digestion requires the presence of both pepsin and HCl because pepsin needs an acidic environment to be able to "work" or do its job. Pepsin needs an environment with a pH around 2, which is roughly the pH of HCl. Therefore, HCl aids pepsin in protien digestions by creating an optimal environment for pepsin to work and digest proteins.
The optimal pH for pepsin and rennin is about the same, 2.0 and 3.4 respectively. Pepsin is slightly more acidic.
Pepsin is the powerful enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, or dairy products in the stomach. Since animals have stomachs, they therefore have pepsin.
it depends on the concentration of NaOH, pepsin, buffer used, ... that cannot be answered in that way...
Pepsin helps the body break down protein in the human body.
Pepsin helps the body break down protein in the human body.
Pepsin is an enzyme whose responsibility it is to break down proteins in the body. Pepsin is not produced by the pancreas; it is produced by the stomach.
Human anatomy
in the stomach
No Gland produces Pepsin, however the Stomach produces Pepsin to break down proteins when you eat a steak for example.
amylase, cellulase, lactase, maltase, protease and sucrase
Dna?
it is found in the stomach of diffrent animals
mouth
Pepsin is a digestive protease released by the chief cells in the stomach that functions to degrade food proteins into peptides
Breaks down the proteins into peptide chains
