carboxypeptidase A

carboxypeptidase B

Question 8

intestine enzymes

Answer 8

aminopeptidase

dipeptidase

Question 9

وين ببلش هضم البروتين

Answer 9

stomach ( gastrin → HCL )

HCL convert pepsinogen to pepsin

Question 10

pepsinogen secreted from

Answer 10

chief cells ,has autocatalysis

renin

Answer 11

Chymosin
curdling milk
convert casein to paracasein
paracasein +Ca+2→ calcium paracasein
