Question

emulsification breaks up ______ into smaller particles.
a protein
b fat
c carbohydrates
d glucose

Explanation:

Emulsification is a process in digestion. Bile salts (produced by the liver and stored in the gallbladder) are involved in emulsification. Fat globules are large and not easily digested by lipases (fat - digesting enzymes). Emulsification breaks large fat globules into smaller fat droplets. This increases the surface area for lipase action. Proteins are broken down by proteases (e.g., pepsin, trypsin), carbohydrates by carbohydrases (e.g., amylase), and glucose is a simple sugar (a monomer of carbohydrates) that does not need emulsification.

Answer:

B. fat
