Answer:

Emulsifier generally reduces the surface tension of the lipid  there by helping in the digestion of the lipid molecules.

Explanation:

Bile that is secreted from liver act as emulsifier because the bile helps in the break down of lipid into small molecules to form micelle thereby reducing the surface tension of the lipid molecules.

                  Due the formation of micelle the broken down lipid molecules binds to the active site of the lipase enzyme and get digested to form fatty acid and glycerol.
