Q. Consider the following enzymes:
  1. Pancreatic Lipase
  2. Pepsin
  3. Trypsin
  4. Invertase
Which of the above enzymes function best in an acidic environment?
Answer: Only 2 and 4
Notes: Pepsin is a digestive enzyme in the stomach that works optimally in acidic pH. Invertase, present in many organisms, also shows best activity in acidic conditions. Pancreatic lipase and trypsin require basic (alkaline) pH to function. Thus, only pepsin and invertase are primarily active in acidic environments among the enzymes listed.
