SINGLE CELL PROTEIN (SCP) - UNSOLVED PRACTICE SET
Topic: Single Cell Protein SCP
Multiple Choice Questions
Q1. Single Cell Protein (SCP) refers to:
- Protein extracted only from animal muscle tissue
- Protein-rich biomass obtained from the mass cultivation of microorganisms such as algae, bacteria, or fungi
- A synthetic chemical protein compound
- A type of plant seed protein only
Q2. One of the main advantages of producing SCP is that microorganisms:
- Grow very slowly, requiring years to produce useful biomass
- Can multiply rapidly and produce large amounts of protein-rich biomass in a relatively short time
- Require vast amounts of agricultural land, similar to livestock
- Cannot be grown using waste materials
Q3. Spirulina, often cited as an example of SCP, is a type of:
- Bacterium
- Alga
- Fungus
- Virus
Q4. SCP production is considered especially useful for addressing:
- Excess food supply
- Protein malnutrition, by providing an alternative protein source
- Water scarcity only
- Soil fertility issues only
Q5. SCP can potentially be produced using which of the following as a growth substrate?
- Only fresh drinking water
- Industrial and agricultural waste materials
- Only pure glucose solutions with no other input
- Only seawater with no nutrients
Short Answer Questions
Q6. Define Single Cell Protein (SCP), and give one example of a microorganism used to produce it.
Q7. Mention any two advantages of using microorganisms, rather than traditional crops or livestock, to produce protein-rich food supplements.
Q8. Why is SCP considered a potential solution to protein malnutrition in growing populations?
Q9. What role can waste materials play in the production of SCP?
Long Answer Questions
Q10. Explain the concept of Single Cell Protein (SCP), describing how it is produced and why microorganisms are particularly suited for this purpose.
Q11. Discuss the advantages and potential significance of SCP as an alternative protein source, especially for addressing global protein malnutrition.
APPLICATION / ANALYSIS
Q12. A company sets up a facility to cultivate Spirulina in large open ponds, using it to produce protein-rich food supplements for distribution in regions facing protein malnutrition. Explain, using your understanding of SCP, why this approach could be more resource-efficient than traditional livestock farming for producing protein.
Q13. Researchers are exploring the use of agricultural waste, such as leftover plant material, as a growth medium for SCP-producing microorganisms. Explain the potential dual benefit of this approach, considering both waste management and food production.
