BIOD 171 Essential
Microbiology Portage Learning
Module 3 Exam Questions and
Answers 100% correct!!
The study of microbes (microorganisms and viruses) and their biological
processes - ANSWER ✔✔Microbiology
What is the smallest biological unit of life - ANSWER ✔✔A cell
Classified as a complex molecule that is composed from smaller subunits
- ANSWER ✔✔Macromolecule
What are the four main types of macromolecules? - ANSWER
✔✔Proteins, carbohydrates, lipids and nucleic acids
,What various functions do proteins have in a cell? - 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 re the two major types of nucleic acids and their roles? -
ANSWER ✔✔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.
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 lipids
, (hydrophobic hydrocarbons) - ANSWER ✔✔Plasma membrane and
what it is made up of
carbon, hydrogen and oxygen atoms. Examples would include, C6H10O5
(glucose) C12H22O11 (surcose) and C6H10O5 (cellulose) - ANSWER
✔✔The three main components of carbohydrates
Contain a nucleus, a membrane enclosed region within the cell that
contains the genetic material. - ANSWER ✔✔Eukaryotic cells
Cells do not contain a nucleus and can be further classified as either
Bacteria and Archaea - ANSWER ✔✔Prokaryotic cells
Coccus (round/spherical), bacillus (rod), Vibrio (curved rod) or spirillum
(spiral/corkscrew) - ANSWER ✔✔Main morphologies of bacteria
Which group of microbes is noted for its ability to survive under harsh
conditions? - ANSWER ✔✔Archaea. They are able to survive in
extremely harsh environmental conditions such as high salt levels, acid
conditions, high temperatures and oxygen-poor conditions
Animal, Plant, Fungi or Protista - ANSWER ✔✔The four main
classifications of Eukarya?
