Q

Descrieti imaginea plus etapele digestiei lipidelor(3)

A

Etapele digestiei lipidelor
I emulsiinarea lipidelor de catre saruri biliare

2 picaturi de grasime(trigliceride)
3 canal biliar
4 de la fixat si vezica biliara
5 micelii (saruri biliare, lecitina, colesterol)
6 picaturi se grasime emulsionate
7 lipaza
