Question

Consider the following and choose the correct answer Assertion [A]: Product inhibition can reduce overall process productivity. Reason [R]: Accumulated products may interfere with enzyme activity or cell viability. The correct answer is

• A. Both [A] and [R] are true and [R] is the correct explanation of [A]
• B. Both [A] and [R] are true and [R] is not the correct explanation of [A]
• C. [A] is true, but [R] is false
• D. [A] is false, but [R] is true

Hint:

Product inhibition occurs when the accumulated product inhibits \[ \boxed{ \text{enzyme activity and/or microbial growth,} } \] thereby reducing fermentation efficiency.

Answer 1

The Correct Option is A

Step 1: Examine the assertion. Accumulation of the desired product during fermentation can inhibit microbial growth or enzyme activity, thereby reducing the overall productivity of the process. Hence, \[ \boxed{\text{Assertion [A] is true}.} \]

Step 2: Examine the reason. Many accumulated products act as inhibitors by affecting enzyme function or decreasing cell viability. Thus, \[ \boxed{\text{Reason [R] is true}.} \] The reason correctly explains why product inhibition lowers process productivity. Therefore, \[ \boxed{(A)} \] is the correct answer.
