Bioreactors starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Bioreactors.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe one advantage of using a bioreactor over traditional batch culture methods.
Describe one challenge in scaling up a bioreactor from laboratory to industrial scale.
Describe the function of a cooling jacket in a bioreactor.
Describe the main advantage of using a chemostat over a batch bioreactor.
Describe the purpose of a foam control system in a bioreactor.
In a scenario where a pharmaceutical company wants to produce insulin using genetically engineered bacteria, which equipment would they most likely use?
A biotechnology company is optimizing the production of a recombinant protein in a bioreactor. They observe that increasing the agitation speed improves oxygen transfer but decreases the yield of the protein. Explain the possible reasons for this observation.
