If bile does not reach the small intestine, why will fat digestion become difficult?
Answer and explanation
Correct answer: Fat will not be emulsified into small droplets, so enzyme action will be less effective.
The governing concept is emulsification during fat digestion. Bile does not digest fat directly, but its bile salts divide large fat globules into many tiny droplets. This increases the surface area available to lipase, allowing the enzyme to work more efficiently in the watery intestinal contents. Thus option A is correct. The other choices describe no role of bile or make biologically impossible claims.
