This set of Basic Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Bioprocess Technology – Scale-Up”.
1. What does bioprocess involve?
a) Complete living cell
b) Viroid
c) Mycoplasma
d) Virus
View Answer
Explanation: Bioprocess is also called fermentation technology. It involves living cells. They are mostly plant, mammalian or microbial.
2. What can enzymes be precisely called as?
a) Biocatalyst
b) Biochemical
c) Chemical
d) Organelle
View Answer
Explanation: Enzymes are biocatalyst. They catalyze the biological reactions. Enzymes helps in the formation of essential products.
3. Vaccines and antibiotics can be made by bioprocess technology only.
a) True
b) False
View Answer
Explanation: Many bioprocessing techniques are used industrially because they are the only practical way for the production of specific products. Such product are vaccines and antibiotics. It still has to compete with chemical processes.
4. Design of vessels for biochemical processes is studied under __________
a) Human physiology
b) Biochemical engineering
c) Immunology
d) Microbiology
View Answer
Explanation: Biochemical engineering covers the designing of instruments and apparatus. Those suitable for carrying biochemical reactions are studied. Biochemical transformations are also studied.
5. Which among the following is not a fermentation technology product?
a) Cheese
b) Sauerkraut
c) Soya sauce
d) Coffee
View Answer
Explanation: Fermentation technology is now called bioprocess technology. It uses microbes for obtaining fermented products. General products are cheese, sauerkraut, soya sauce and some pickles.
6. Which among the following cannot be termed as a beverage?
a) Beer
b) Wine
c) Pickle
d) Coffee
View Answer
Explanation: Beverages include drinkables like beer, wine and coffee. Fermented beverages include beer and wine. Some might be alcoholic.
7. Microbes do not play a specific role in __________
a) Software development
b) Water purification
c) Effluent treatment
d) Solid waste management
View Answer
Explanation: Microbes play a role in removing obnoxious and unhealthful wastes. They are now used in water purification, effluent treatment and solid waste management. They do not play any role in software development.
8. Bioprocessing involves multitude of complex enzyme-catalyzed reactions within ________
a) cellular systems
b) primitive environment
c) software platforms
d) launch systems
View Answer
Explanation: Bioprocessing involves multitude of enzymes. These enzymes catalyze reactions within cellular systems. These reactions are dependent on physical and chemical environment.
9. The diagram below graphically represents the growth of microbes in a nutrient medium. What is phase 5?
a) Lag phase
b) Exponential phase
c) Death phase
d) Stationary phase
View Answer
Explanation: Phase 1 and 2 are lag phase and transient acceleration. Phase 3 and 4 represent exponential phase and deceleration phase. The last 2 phases are stationary phase and death phase.
10. What cultivation of microbes gives near balanced growth?
a) Continuous
b) Disrupted
c) Harmonic
d) Symphonic
View Answer
Explanation: Batch conditions are in contrast to continuous. Continuous cultivations give a near balanced growth. It is with a little fluctuation of nutrients and biomass.
11. Which method of cultivation lets the microbes grow steadily?
a) Continuous
b) Subordinate
c) Coordinate
d) Inhibitory
View Answer
Explanation: Continuous methods of cultivation permit the microbes to grow under steady state. Steady state is defined as unchanging condition. Growth occurs in a constant rate in a constant environment.
12. What kind of medium is generally passed into the bioreactor?
a) Contaminated
b) Partially contaminated
c) Chemical
d) Sterile
View Answer
Explanation: In a culture system, sterile medium is passed into the bioreactor. Microbes grow on the medium. A steady flow rate of culture broth emerges.
