hard Q9 of 15
General Science - Physics (Basics)
Which of the following correctly describes the role of the enzyme lipase in digestion?
ABreaks down fats into glycerol and fatty acids
BConverts starch into maltose
CEmulsifies fats into smaller droplets
DBreaks down proteins into amino acids
Step-by-Step Solution
  1. Step 1: Understand lipase function

    Lipase is an enzyme that breaks down fats into glycerol and fatty acids during digestion.
  2. Step 2: Clarify difference between emulsification and digestion

    Emulsification of fats is done by bile salts, not lipase; lipase chemically breaks down fats.
  3. Step 3: Eliminate other options

    Breaking proteins is done by proteases; starch digestion is by amylase; emulsification is a physical process, not enzymatic digestion.
  4. Final Answer:

    Breaks down fats into glycerol and fatty acids → Option A
  5. Quick Check:

    Lipase function = Fat breakdown into glycerol and fatty acids ✅
Quick Trick: Bile emulsifies fats; lipase digests fats chemically
Common Mistakes:
MISTAKES
