2. Saccharomyces cerevisiae, used as a source of single-cell protein, belongs to which group?
A.
Algae
B.
Bacteria
C.
Fungi
D.
Protozoa
Correct Answer:
Fungi
Explanation:
Saccharomyces cerevisiae is a yeast, and yeasts are unicellular fungi that can be used to produce single-cell protein.
3. Which organism is a yeast commonly associated with fungal single-cell protein production?
A.
Candida utilis
B.
Spirulina maxima
C.
Chlorella vulgaris
D.
Methylomonas clara
Correct Answer:
Candida utilis
Explanation:
Candida utilis is a yeast used as a fungal source of microbial protein.
4. Fungal single-cell protein is commonly obtained from which type of organism?
A.
Yeast
B.
Virus
C.
Moss
D.
Fern
Correct Answer:
Yeast
Explanation:
Yeasts are unicellular fungi and are important fungal sources of single-cell protein.
5. Which fungal organism is used in the production of the mycoprotein food known as Quorn?
A.
Fusarium venenatum
B.
Candida albicans
C.
Rhizopus stolonifer
D.
Penicillium notatum
Correct Answer:
Fusarium venenatum
Explanation:
Fusarium venenatum is a filamentous fungus used to produce mycoprotein, a fungal protein food.
6. The term mycoprotein refers to protein obtained mainly from which source?
A.
Fungi
B.
Green algae
C.
Cyanobacteria
D.
Insects
Correct Answer:
Fungi
Explanation:
Mycoprotein is protein-rich biomass produced from fungi, making fungi an important source of single-cell protein.
7. Which of the following is a unicellular fungus suitable for use as single-cell protein?
A.
Saccharomyces cerevisiae
B.
Nostoc commune
C.
Chlorella pyrenoidosa
D.
Lactobacillus bulgaricus
Correct Answer:
Saccharomyces cerevisiae
Explanation:
Saccharomyces cerevisiae is a unicellular yeast and therefore serves as a fungal source of single-cell protein.
8. Why are yeasts useful as fungal sources of single-cell protein?
A.
They can grow rapidly and form protein-rich biomass
B.
They produce seeds in large numbers
C.
They obtain protein by photosynthesis only
D.
They are multicellular flowering plants
Correct Answer:
They can grow rapidly and form protein-rich biomass
Explanation:
Yeasts multiply rapidly and their biomass contains substantial protein, making them useful for single-cell protein production.
9. Which fungal source of single-cell protein is also called baker's yeast?
A.
Saccharomyces cerevisiae
B.
Fusarium venenatum
C.
Candida utilis
D.
Aspergillus niger
Correct Answer:
Saccharomyces cerevisiae
Explanation:
Saccharomyces cerevisiae is commonly known as baker's yeast and can also be used as a fungal protein source.
10. Fungal biomass used as single-cell protein is mainly valued because it is rich in which nutrient?
A.
Protein
B.
Starch only
C.
Chlorophyll
D.
Cellulose only
Correct Answer:
Protein
Explanation:
Fungal biomass, especially yeast biomass, is valued as single-cell protein because it contains a high proportion of protein.
