Model Answer

(b) Bile juice breaks large fat globules into smaller ones (emulsification) and makes the medium alkaline for pancreatic enzymes to act.

Source: Life Processes, Section 5.2.4

Explanation

The textbook clearly states that bile juice from the liver: (1) makes the acidic food from the stomach alkaline, and (2) breaks large fat globules into smaller ones (emulsification) — it does not contain enzymes. Lipase is secreted by the pancreas, not bile. Villi absorb food; they are not a function of bile. Pepsin digests proteins in the stomach, not bile.
