Portage Learning
This Portage Learning Microbiology (BIOD 171) final exam is a comprehensive,
timed test covering everything from cellular structures and microbial metabolism to
virology and immunology. It heavily features multiple-choice, matching, short-essay,
and disease-identification questions.
🦠 Core Exam Topics & Question Types
Cellular Structures & Microscopy: Questions matching organelles (e.g.,
ribosomes, nucleus, lysosomes) to their functions. You will also need to describe
microscopy techniques, such as how a Scanning Electron Microscope (SEM)
produces 3-D images.
Microbial Genetics & Metabolism: Frequently includes questions on DNA vs.
RNA differences, ATP yields, and byproducts of the TCA cycle.
Microbial Growth: You will likely be asked to explain the quadrant streak plate
method (used to isolate pure colonies) and the purpose of using wet mounts to
observe motility.
Virology & Vaccines: Questions often cover viral structures (e.g., hemagglutinin
and neuraminidase proteins in Influenza) and the differences between various
vaccines, like the Salk and Sabin polio vaccines.
Immunology & Diseases: You will need to identify specific diseases based on
their physical manifestations or characteristics, such as distinguishing between
different STDs (e.g., Gonorrhea or Chlamydia) or bacterial types (e.g.,
Mycobacterium tuberculosis using acid-fast staining).
Quiz_________________?
Match each of the following organelles with the correct description.
1
,Ribosomes
nucleus
cytoplasm
lysosomes -
Answer
Ribo - funtion in protein synthesis
nucleus - contains genomic content
cyto - constitutes the open volume
lyso - contains hydrolytic enzymes
Quiz_________________?
Briefly explain how a Scanning Electron Microscope (SEM) forms an
image of subcellular organelles, substrates, and viral particles. -
Answer
An image is formed from the interactions of electrons
as they reflect off (not through) the surface of the specimen.
Samples are coated in either gold or palladium to enhance
electron reflections. The reflection is seen in 3-D rendering.
OR
A scan (image) as electrons reflect off surfaces of a specimen loaded into the machine. In order
for this to best work, any sample is coated in gold or other refractive material to enhance
reflections. SEM is shown in 3-D
Quiz_________________?
Match each of the following organelles with the correct description.
2
, Nucleus
Endoplasmic Reticulum
Lysosomes
Chloroplasts -
Answer
Nucleus - Contains genomic content of the cell
Endoplasmic Reticulum - Series of membrane-enclosed sacs and interconnected tubes
Lysosomes - Contain hydrolytic enzymes capable of degrading unwanted cellular debris
Chloroplasts - Site of photosynthesis
