BIOD 171 Essential Microbiology Final Exam
2025/2026|GUARANTEED PASS
1. True or False: A virus is considered a microorganism.
False. Viruses are not living and as such are not considered microorganisms. Viruses
can, however, be classified as microbes, a more general term that includes
microorganisms and viruses.
2. What is the smallest biological unit of life?
A cell.
3. At a generalized level, all cells are comprised of what?
Macromolecules*
*A student may also answer: Proteins, Lipids, Nucleic acids and Polysaccharides but they
must answer with all four to be fully correct.
1. Animalia, Plantae, Fungi and Protista are all classification under what type of
organism?
A. Bacteria
B. Eukarya
C. Archaea
D. Virus
B. Only Eukarya contains animals, plants, fungi and protists.
2. All multicellular microorganisms classified as Animalia are autotropic.
, False—they are heterotropic.
3. Microorganisms classified as obtain most of their energy by converting
light energy into chemical energy.
Plantae
1. Define catabolism.
Catabolism is the process of breaking down larger molecules into useful energy
sources.
2. Upon cellular injury, which metabolic process is involved during the growth and
repair phases of the cell?
The anabolic process would be active as it (by definition) is involved in the building
up of small complexes into larger complexes.
1. What is one of the main functions of light reactions?
Similar to the electron transport chain, one of its main functions is to generate a proton
concentration gradient to generate ATP.
2. True or False: Dark reactions can occur in the presence or absence of light.
True. The term ‘dark reactions’ (also known as the Calvin Cycle) simply denotes the
second stage in photosynthesis—dark reactions do not actually require darkness in
order to occur.
