Question

Why are extracellular enzymes preferred in industrial production?

• A. Higher molecular weight
• B. Require cell disruption
• C. Easier purification
• D. Low stability

Hint:

Extracellular enzymes are preferred because they \[ \boxed{ \text{are secreted into the medium and require simpler purification.} } \] Intracellular enzymes require cell lysis before purification.

Answer 1

The Correct Option is C

Step 1: Recall the difference between intracellular and extracellular enzymes. Extracellular enzymes are secreted directly into the culture medium. Therefore, they can be recovered without breaking the cells.

Step 2: Identify the advantage. Since cell disruption is unnecessary, downstream processing becomes simpler and purification is easier. Hence, \[ \boxed{\text{Easier purification}} \] is the correct answer. Therefore, \[ \boxed{(C)} \] is the correct answer.
