MCQ Questions
1. What does the term Single Cell Protein (SCP) refer to?
A.
Protein obtained from single-celled or microscopic organisms
B.
Protein obtained only from animal muscles
C.
Protein produced by flowering plants
D.
Protein formed from mineral salts
Correct Answer:
Protein obtained from single-celled or microscopic organisms
Explanation:
Single Cell Protein refers to protein-rich biomass obtained from microorganisms such as single-celled organisms or other microscopic organisms.
2. Why is it called Single Cell Protein?
A.
It is made from one type of amino acid
B.
It is obtained from microorganisms consisting of single cells or microscopic biomass
C.
It contains protein in only one cell of an organism
D.
It is produced from a single plant leaf
Correct Answer:
It is obtained from microorganisms consisting of single cells or microscopic biomass
Explanation:
The name Single Cell Protein is used because the protein-rich material is derived from microorganisms, many of which are single-celled.
3. Which of the following is the best definition of Single Cell Protein?
A.
A protein-rich microbial biomass used as a protein source
B.
A carbohydrate stored in plant cells
C.
A vitamin obtained from animal tissues
D.
A mineral mixture prepared in laboratories
Correct Answer:
A protein-rich microbial biomass used as a protein source
Explanation:
Single Cell Protein is defined as protein-rich biomass produced from microorganisms and used as a source of protein.
4. Single Cell Protein is mainly associated with which type of biological material?
A.
Microbial biomass
B.
Rock particles
C.
Plant fibre only
D.
Animal bones only
Correct Answer:
Microbial biomass
Explanation:
SCP consists of the protein-rich biomass of microorganisms, so it is mainly associated with microbial biomass.
5. Which organisms can generally provide Single Cell Protein?
A.
Microorganisms
B.
Only large mammals
C.
Only flowering plants
D.
Only reptiles
Correct Answer:
Microorganisms
Explanation:
Single Cell Protein is obtained from microorganisms, including microscopic organisms that produce protein-rich biomass.
6. What is the main component of Single Cell Protein biomass?
A.
Protein
B.
Wax
C.
Silica
D.
Starch crystals only
Correct Answer:
Protein
Explanation:
The biomass is called Single Cell Protein because it contains a high proportion of protein derived from microorganisms.
7. The abbreviation SCP stands for what?
A.
Single Cell Protein
B.
Simple Chemical Product
C.
Stored Cell Pigment
D.
Synthetic Carbon Particle
Correct Answer:
Single Cell Protein
Explanation:
SCP is the standard abbreviation for Single Cell Protein, which is protein-rich microbial biomass.
8. Single Cell Protein is best described as a product obtained from which source category?
A.
Microbial cells and their biomass
B.
Metal ores
C.
Plastic materials
D.
Animal fats only
Correct Answer:
Microbial cells and their biomass
Explanation:
SCP is obtained from microbial cells or the protein-rich biomass produced by microorganisms.
9. Which statement about Single Cell Protein is correct?
A.
It is protein derived from microorganisms
B.
It is a type of mineral nutrient
C.
It is a nucleic acid found only in humans
D.
It is a structural fibre of wood
Correct Answer:
It is protein derived from microorganisms
Explanation:
The defining feature of Single Cell Protein is that it is protein obtained from microorganisms.
10. What does the word 'single' in Single Cell Protein primarily indicate?
A.
The involvement of single-celled microorganisms
B.
The presence of only one protein molecule
C.
The use of one animal species
D.
The use of one chemical element
Correct Answer:
The involvement of single-celled microorganisms
Explanation:
The word 'single' refers mainly to the single-celled microorganisms from which the protein-rich biomass is obtained.
