Question

Which action taking place in the digestive system of humans is similar to the emulsifying action of soaps on dirt?

• A. Bile salts breaking large fat globules into smaller ones
• B. Bile juice enzymes helping in digestion of starch
• C. Bile juice providing acidic medium
• D. Bile juice providing alkaline medium

Answer 1

Answer:

A. Bile salts breaking large fat globules into smaller ones

Bile salts in the digestive system emulsify fats, breaking down large fat globules into smaller droplets, similar to how soap emulsifies and removes dirt. In the human digestive system, the action of bile salts is similar to how soap emulsifies grease. Bile salts help break down large fat globules into smaller droplets, increasing the surface area for fat-digesting enzymes, such as lipase, to act upon.
