Question

What are two ways that protein digestion similar from carb digestion?

Answer 1

mechanical and chemical digestion are the two ways of protein digestion

mechanical digestion strats from mouth .break down of food into small piece by teeth .saliva helps in lubrication and swallowing .through oesophagus it enters stomach . gastric juice containing hcl and enzyme pepsin .acidity unfolds the protein and pepsin initiates the breakdown of protein ,the powerful mechanical contraction of stomach churns food .stomach empties this in to small intestine the 2 major pancre4atic enzymes are trypsin and chymotrypsin .muscle contraction of small intestine propel the digested protein in to absorptrion site . the aminoacids from proteins absorbed in to blood in lower portion of small intestine . once they are in blood they transported to liver .in liver catabolism of aminoacid and release of ammonia takeplace .ammonia then converted to urea and excreated in urine
