QUESTIONS AND ANSWERS 2025
a) Microbiology is the study of what? - CORRECT-ANSWERSMy answer: Microbiology is
the study of microorganisms and their biological processes at what is called the "micro"
or "microscopic" level.
b) Answer Key: Microbiology is the study of microbes (microorganisms and viruses) and
their biological processes.
c) What is the smallest biological unit of life? - CORRECT-ANSWERSthe cell
d) What is a macromolecule? - CORRECT-ANSWERSMy answer: Macromolecules are
large and complicated molecules that are made up of smaller molecules. Examples of
macromolecules are polysaccharides, lipids, nucleic acids, and proteins.
e) More info:
- Proteins are made up of amino acids (of which there are 20 different types).
- Nucleic Acids can be either DNA or RNA. Nucleic acids are made up of
nucleotides. For DNA, the nucleotides are adenine (A), guanine (G), cytosine (C)
and thymine (T). For RNA, the nucleotides are adenine (A), guanine (G), cytosine
(C) and uracil (U).
- Lipids are made up of hydrocarbons.
- Polysaccharides are made up of monosaccharides.
, f) Answer Key: A macromolecule is classified as a complex molecule that is composed
from smaller subunits.
g) What are the four main types of macromolecules? - CORRECT-ANSWERSMy answer:
polysaccharides, lipids, nucleic acids, proteins
h) Answer Key: Proteins, nucleic acids, lipids and polysaccharides
i) What various functions do proteins have in a cell? - CORRECT-ANSWERSMy Answer:
j) Proteins have several functions in the cell;
1. To assist materials in moving in and out of the cell
2. To act as a catalyst enzyme which speeds up a biochemical process
3. To provide structure in the cell
4. To enable movement (e.g. filaments)
k) Answer Key: Proteins may facilitate the movement of materials in or out of a cell. Some
can act as enzymes that catalyze, or speed up, biochemical processes. Others play a
structural role while other proteins, such as filaments, enable movement.
l) What are the two major types of nucleic acids and their roles? - CORRECT-
ANSWERSMy Answer: The two major types of nucleic acids and their roles are as
follows;
1. DNA: Deoxyribonucleic acid
m) DNA is located in the nucleus of the cell. DNA's role in the cell is to store hereditary
information.
