NEET Zoology (general) MCQ Question
Which of the following statements about bioreactors and their functionalities is correct?
Bioreactors require an oxygen delivery system and temperature control system for optimal microbial growth.
Bioreactors can only operate with a solid base and do not utilize stirrers for mixing.
The agitator system in a bioreactor is only used for mixing, without any impact on oxygen availability.
Downstream processing occurs simultaneously with the biosynthetic stage in a bioreactor.
Correct Answer
Detailed Explanation
A bioreactor is equipped with an oxygen delivery system and a temperature control system to facilitate optimal growth conditions for microorganisms, as described in the NCERT context. Option B is incorrect because bioreactors can have various designs, including cylindrical shapes that facilitate mixing. Option C is misleading as the agitator system also aids in oxygen availability. Option D is incorrect since downstream processing occurs after the biosynthetic stage.
