Portage Learning: Microbiology Module
1 Questions and Answers Graded A+
Microbiology is the study of what? - Correct answer-Microbiology is the study of
microbes (microorganisms and viruses) and their biological processes.
What is the smallest biological unit of life? - Correct answer-A Cell
What is a macromolecule? - Correct answer-A macromolecule is classified as a
complex molecule that is composed from smaller subunits.
What are the four main types of macromolecules? - Correct answer-1.
Carbohydrates
2. Lipids
3. Proteins
4. Nucleic Acids
What various functions do proteins have in a cell? - Correct answer-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.
What are the two major types of nucleic acids and their roles? - Correct answer-
There are two major types of nucleic acids: DNA (deoxyribonucleic acid) and
RNA (ribonucleic acid). Nucleic acids are chemical molecules that carry genetic
information within the cell. DNA contains a vast amount of hereditary information
and is responsible for the inheritable characteristics of living organisms. RNA is
responsible for deciphering the hereditary information in DNA and using it to
synthesize proteins.
What is the plasma membrane, and what is it made up of? - Correct answer-The
plasma membrane serves the cell as a surrounding barrier that separates the inside
of the cell from the outside surrounding environment. The plasma membrane also
restricts the movement of materials (water, nutrients, etc) either in or out of the
cell, thus allowing a cells to absorb and keep what is needed (influx) while also
preventing the escape (out flux) of essential nutrients. The plasma membrane is
composed of lipids (hydrophobic hydrocarbons).
What are the three main components of polysaccharides? - Correct answer-
Polysaccharides are composed of carbon, hydrogen and oxygen atoms. Examples
