2a )
Enzyme is a substance produced by a living organism
which acts as a catalyst to bring about a specific
biochemical reaction.
2aii )
i)all enzymes are proteins .
ii )Enzymes possess great catalytic power .
iii )Enzymes are highy specific .
iv )Enzymes show varying degree of specificities .
v )Absolute specificity where the enzymes
react specifically with only one substrate.
2b )
Pancreatic fluid or juice contains digestive enzymes
that pass to the small intestine where they help to
further break down the carbohydrates , proteins, and
lipids (fats ) in the chyme. Pancreatic juice is a liquid
secreted by the pancreas , which contains a variety of
enzymes including trypsinogen,chymotrypsinogen ,
elastase , carboxypeptidase , pancreatic lipase,
nucleases, and amylase . Pancreatic juice is alkaline
in nature due to the high concentration of
bicarbonate ions . This is useful in neutralizing the
acidic gastric acid, allowing for effective enzymic
action.
