Secondly, the pancreas releases pancreatic juice consisting of amylase, tripsin, chymotripsin and lipase into the duodenum.
Enzymes in Biotechnology Enzymes are globular proteins used as biological catalysts, they speed up the rate of chemical reactions. The essential role of the enzyme is to provide an active site, which has a complimentary shape to the molecules that bind there. Substrates are converted to products through the formation of an enzyme-substrate complex. To be effective in a production process the.
