(ii) Digestive secretion of liver contains which salts? What is their function?

Explanation

(i) Liver secretes bile. It is stored in gall bladder. Bile secretions contain no enzymes.
(ii) Bile contains salts, namely sodium glycocholate and sodium taurocholate. These reduce the surface tension of large fat droplets break them into many small ones. The process is called emulsification. Bile salts also form a thin coating around tiny fat droplets to keep them away from coalescing.
