The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes.
