An enzyme used to decompose the lipids into fatty acids in our alimentary canal is
Correct answer: C. Lipase
- A. Amylase
- B. Protease
- C. Lipase
- D. Urease
Explanation
Pancreatic lipase hydrolyses triglycerides into fatty acids and glycerol in the duodenum, working on the enormous surface created after bile salts have emulsified the fat. Amylase acts on starch and protease on protein, each enzyme being specific to one class of substrate. Urease breaks urea down and is found in bacteria and plants rather than the human gut.

About Enzymes as Biocatalysts
Enzymes are protein or RNA biocatalysts that lower activation energy without being consumed, and their active sites bind specific substrates. The topic covers the lock and key and induced fit models, effects of temperature, pH and substrate concentration, cofactors, enzyme specificity, and competitive versus non-competitive inhibition.
