PRE EXAM FINAL FORMAT.
A virus is classified as a microbe.
True. Although viruses are not living and as such are not considered microorganisms, they
can, however, be classified as microbes, a more general term that includes microorganisms
and viruses.
2. True or False: The smallest biological unit of life is the molecule.
False. The smallest biological unit of life is the cell.
3. What are the 4 main types of macromolecules found in cells?
Proteins, Lipids, Nucleic acids and Polysaccharides
Answer Key
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.

, PRE EXAM FINAL FORMAT.
Anabolism is the process of building up or biosynthesis of macromolecules from small
molecular units into much larger complexes.
2. In order to convert proteins into amino acids which metabolic process would be active?
Catabolism would be active as proteins are made up of amino acids. Therefore the process
described (proteins into amino acids) is the breakdown, or catabolism of protein.

Answer Key
1. In phosphorylation, the light reactions always occur where?
The process of converting light energy into chemical energy (photophosphorylation) always
occurs in the membrane.
2. True or False: The Calvin cycle must occur in the absence of light.
False. 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.

Answer Key
1. Assuming a constant (non-adjustable) light source power, identify the part of the microscope you
would adjust to limit the amount of light entering the microscope.
Select all that apply.
A. Objective
B. Condenser
C. Iris diaphragm
D. Eye piece
C. The iris controls the amount of light that passes through the sample and into the objective
lens. Thus, it can be adjusted (opened or closed) to alter the amount of light.
2. What is the total magnification (relative to your eye) of a sample imaged with a 60x objective and
a 10x eyepiece? Show your math.
