Biotechnological Production of Enzymes 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 Biotechnological Production of Enzymes.
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 environmental benefit of using biotechnologically produced enzymes in industry.
Describe one method used to increase the yield of enzyme production in microbial cultures.
Describe the importance of substrate specificity in industrial enzyme applications.
Describe the role of fermentation in the biotechnological production of enzymes.
Describe the role of gene cloning in the production of industrial enzymes.
Explain the difference between extracellular and intracellular enzyme production in biotechnology.
A biotechnology company is developing a new enzyme for use in the paper industry. The enzyme must be active at high pH and resistant to degradation by chemicals used in bleaching. Describe two genetic engineering strategies that could be used to enhance these properties in the enzyme.
A researcher is comparing two microbial strains for enzyme production. Strain A produces a high yield of enzyme but also secretes a protease that degrades the target enzyme. Strain B produces a lower yield but does not secrete proteases. Propose a biotechnological solution to improve enzyme yield in Strain A.
