Answer:
False
Explanation:
Chief cells usually secrete pepsinogen, but the product does not related is to acidity.therefore, Whenever
HCl secreted by the parietal cells activate pepsinogen, the pepsinogen is converted into pepsin, and pepsin is an enzyme that acts on proteins.
NOTE:
The gastric chief cell is one of the cells in our stomach that brings about the release of pepsinogen and chymosin. Pepsinogen is activated into the body's digestive enzyme pepsin and the pepsin will have contact with acid that is produced by gastric parietal cells.
Pepsinogen is substance that is secreted into gastric juice from both mucous cells and chief cells. After secretion pepsinogen is activated into the active protease pepsin by the stomach acid.the protease pepsin helps the stomach's ability to initiate digestion of proteins.
Answer:
Parasitic flatworms protect themselves from the host's digestive liquids by developing teguments or resistant coverings around their bodies. They secrete anti enzymes to neutralize the digestive juices of host which are produced in intestine where flatworm lives.
