The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Digestion is greatly aided
by emulsification, the
breaking up of fat globules into much smaller emulsion droplets. Bile
salts and phospholipidsare amphipathic molecules that are
present in the bile they stabilize the emulsion so formed.
Motility in the small intestine breaks fat globules apart into small droplets
that are coated with bile salts and phospholipids, preventing the emulsion
droplets from re-associating.
The emulsion droplets are
where digestion occurs. Emulsification greatly increases the surface area where
water-soluble pancreatic lipase can work to digest TAG. Another factor that
helps is colipase, an
amphipathic protein that binds and anchors pancreatic lipase at the surface of
the emulsion droplet.
