colonies to form tissue layers. Answer: True
◉ Microbiology is the study of what? Answer: Microbiology is the
study of microbes (microorganisms and viruses) and their biological
processes.

◉ What is the smallest biological unit of life? Answer: A cell
,◉ What is a macromolecule Answer: A macromolecules is classified
as a complex molecule that is composed of smaller subunits
◉ Identify the following cellular components by matching the number
with the description. Answer: 1) Nucleus
2) Lysosome
3) Plasma Membrane
4) Golgi Aparatus
5) Rough Endoplasmic Reticulum
◉ The combination of the cell membrane and the outer membrane is
referred to as the (select all that apply)
A. Cell Wall
B. Outer leaflet
C. Cell envelope

◉ What are the four main types of macromolecules? Answer: Proteins,
nucleic acids, lipids and carbohydrates

◉ True of False. All multicellular microorganisms classified as Animalia
are heterotropic. Answer: True
◉ 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 is the primary byproduct of the TCA cycle? Select all that apply.
A. FADH2
B. FAD
C. NADH
D. NAD+ Answer: A & C
◉ What are the two major types of nucleic acids and their roles?
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? 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).
◉ In the absence of glucose, which of the following cannot be used as
alternative energy sources? Select all that apply.
A. Carbohydrates
B. Lactose
C. Fatty acid chains
D. Nucleic acids Answer: D.
◉ What are the three main components of polysaccharides? Answer:
Polysaccharides are composed of carbon, hydrogen and oxygen atoms.
Examples would include, C6H12O6 (glucose) C12H22O11 (sucrose)
and C6H10O5 (cellulose).
