by hydrolysis

36
Q

Attractions and interaction between the side chains cause the protein to fold into?

A

Three Dimensional shapes

37
Q

It begins with chewing,tearing, and mixing food with salivary juice to form a bolus

A

Mechanical Digestion of protein

38
Q

It denatures protein and activate pepsinogen to form pepsin

A

Hydrochloric

39
Q

It break the polypeptide chain into smaller polypeptides

A

Pepsin

40
Q

Its enter the small intestine and continue to cleve peptide bonds, resulting in dipeptides, tripeptides and single amino acid

A

Enzyme from the pancreas

41
