Which of the following processes will be affected by the absence of enterokinase?
a)	Lipid Fatty acid + Glycerol	b)	Dipeptides Amino acid
c)	Proteases Dipeptide	d)	Amylase Maltose

(c)

Enterokinase or enteropeptidase is secreted by crypts of Leibrekuhn in the duodenum. It is a serine protease enzyme. When food enters into the duodenum, enterokinase converts proenzyme trypsinogen into trypsin, which indirectly activating a number of pancreatic digestive enzyme.  It also activates other proteases in the pancreatic juice. Thus, absence of enterokinase affects the conversion of proteases intosmall peptides.
