This set of Fermentation Technology Multiple Choice Questions & Answers (MCQs) focuses on “Brewing Yeast – Taxonomy and Location of Enzymes”.
1. What is the location of alcohol acetyltransferase?
a) Lysosomes
b) Microsomes
c) Peroxisomes
d) ER
View Answer
Explanation: Alcohol acetyltransferase is present in microsomes. Microsomes are re-formed pieces of the endoplasmic reticulum (ER) when eukaryotic cells are broken down. They are not present in healthy living cells.
2. Which of the following enzyme is present in the plasma membrane?
a) Invertase
b) Melibiase
c) Steryl-ester hydrolase
d) Hexokinase
View Answer
Explanation: Steryl-ester hydrolase is present in the plasma membrane. Whereas melibiase and invertase are present in periplasm and Hexokinase is present in the cytoplasm of the cell. It helps in the biosynthesis of bile acids.
3. Saccharomyces cerevisiae belongs to the division _____________
a) Oomycota
b) Zygomycota
c) Basidiomycota
d) Ascomycota
View Answer
Explanation: Saccharomyces cerevisiae belongs to the division Ascomycota. The members of division Ascomycota are commonly known as sac fungi or Ascomycetes and it is the largest phylum of Fungi with 64,000 species.
4. Imperfect fungi belongs to ___________
a) Oomycota
b) Zygomycota
c) Basidiomycota
d) Deuteromycota
View Answer
Explanation: Fungi imperfecti belong to Deuteromycota. They do not produce spores and the member of Deuteromycota are known as Deuteromycetes. Penicillium is an example of Deuteromycetes.
5. Oomycota are ______________
a) Parasitic to plants
b) Imperfect fungi
c) Insect parasites
d) Filamentous
View Answer
Explanation: Oomycota is a fungal division that resembles algae and is often parasitic to plants. The member of division oomycota are known as oomycetes and examples are white rust, water mould and downy mildew.
6. Black bread mould is an example of kingdom _____________
a) Basidiomycota
b) Deuteromycota
c) Zygomycota
d) Ascomycota
View Answer
Explanation: Black bread mould is an example of kingdom Zygomycota. The members of kingdom Zygomycota are filamentous and are insect parasites and are referred to as zygomycetes.
7. Which of the following is an example of Basidiomycota?
a) White rust
b) Water mould
c) Corn smut
d) Thrush
View Answer
Explanation: Corn smut is an example of Basidiomycota. It is a type of plant disease caused by the pathogenic fungus. Other examples of Basidiomycota include Sulphur fungus, black stem rust, puffball, etc.
8. Which of the following enzyme is present in Vacuole?
a) Acid trehalase
b) PDH
c) Proline oxidase
d) Fumarase
View Answer
Explanation: Acid trehalase enzyme is present inside the vacuoles. It is an important enzyme which is useful in the conversion of trehalose to glucose. It is also present inside the small intestine of human beings.
9. TCA cycle enzymes are located in ____________
a) Vacuoles
b) Golgi Apparatus
c) Mitochondrial matrix
d) Plasma membrane
View Answer
Explanation: TCA cycle enzymes are located in the mitochondrial matrix. It is the space between the inner membrane of mitochondria and is more viscous than the cytoplasm of the cell.
10. Who is ‘the father of taxonomy’?
a) Lamarck
b) Darwin
c) Linnaeus
d) Leeuwenhoek
View Answer
Explanation: Carl Linnaeus is the father of taxonomy. He was a Swedish botanist, physician, and zoologist who formalized binomial nomenclature, which is the modern system of naming organisms.
11. The group of division is known as ____________
a) Kingdom
b) Family
c) Order
d) Genus
View Answer
Explanation: The group of division is known as the Kingdom. It is ranked just below the domain. The commonly recognized kingdoms are Protista, Animalia, Plantae, and Fungi. The archaea and bacteria are grouped into one kingdom.
12. Which of the following is the method of raising the temperature of mash contents?
a) Underback
b) Underletting
c) Sparging
d) Enzyme addition
View Answer
Explanation: Underletting is the method of raising the temperature of the contents of the mash tun by pumping hot liquor from the base. Underback is a vessel in which sweet wort is collected from the mash tun and held before delivery to the copper. Sparging is the method of providing air to the medium. An enzyme addition is increasing the rate of a reaction.
13. Diazonium is used to differentiate between Ascomycetes and Deuteromycetes.
a) True
b) False
View Answer
Explanation: Diazonium Blue B is used to differentiate between ascomycetes and basidiomycetes. The ascomycetes form asci and basidiomycetes form basidia.
14. Carl Linnaeus first classified organisms.
a) True
b) False
View Answer
Explanation: Aristotle first classified organisms. He developed the system of classification of animals and plants. He is also regarded as ‘the father of science’.
