Cystic fibrosis, a genetic disorder characterized by pulmonary and pancreatic dysfunction, usually appears in young children but can also affect adults. if the pancreas was functioning correctly, where would the bile and pancreatic enzymes enter the gi system?

The part that the bile and pancreatic enzymes enter the GI system is the Duodenum. Duodenum is the first and shortest segment of the small intestine. It receives partially digested food from the stomach and plays a vital role in the chemical digestion of chyme in preparation for absorption in the small intestine. 

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
