What is physiology - ANSWER: study of the vital life processes of organisms.
What is Microbial physiology - ANSWER: It concerns the vital life processes of microorganisms.
How do scientists learn about human cells? - ANSWER: By studying the nutritional needs of bacteria,
their metabolic pathways, and way they live, grow, multiply, or die under certain conditions.
What kind of microorganisms are used extensively in genetic study and why? - ANSWER: Bacteria,
fungi, and viruses because they produce generation after generation so rapidly.
Define protoplasm - ANSWER: the colorless material comprising the living part of a cell, including the
cytoplasm, nucleus, and other organelles.
Name 6 major elements which all living protoplasm contain? - ANSWER: carbon, hydrogen, oxygen,
nitrogen, phosphorus, and sulfur.
What makes up vital macromolecules of life - ANSWER: carbon, hydrogen, oxygen, nitrogen,
phosphorus, sulfur, carbohydrates, lipids, proteins, and nucleic acids.
What are essential nutrients - ANSWER: Materials that organisms are unable to synthesize, but are
required for building macromolecules and sustaining life
E.g., of some essential nutrients - ANSWER: certain essential amino acids and essential fatty acids
What is the source of energy for Phototrophs - ANSWER: Phototrophs use light as an energy source.
What is the source of energy for chemotrophs - ANSWER: Chemotrophs use either inorganic or
organic chemicals as an energy source
Difference b/w Chemolithotrophs & Chemoorganotrophs - ANSWER: Chemolithotrophs use inorganic
chemicals as an energy source.
Chemoorganotrophs use organic chemicals as an energy source.
What is the source of carbon for Autotrophs - ANSWER: CO2
What are autotrophs - ANSWER: Microorganisms whose sole source of carbon is CO2
What is the source of carbon for Heterotrophs - ANSWER: Heterotrophs use organic compounds other
than CO2 as carbon sources.
What are Heterotrophs - ANSWER: The Microorganisms that use organic compounds other than CO2
as carbon sources.
What are Photoautotrophs - ANSWER: uses light as their source of energy
&
CO2 as their source of carbon
What are Chemoautotrophs - ANSWER: use either inorganic or organic chemicals as an energy source
, &
CO2 for their carbon source
What are Chemoheterotrophs - ANSWER: use either inorganic or organic chemicals as an energy
source
&
use organic compounds other than CO2 as carbon sources.
What is ecology - ANSWER: study of the interactions between living organisms and the world around
them
What is an ecosystem - ANSWER: Ecosystem refers to the interactions between living organisms and
their nonliving environment.
What is of prime importance in the functioning of the ecosystem. Give an example - ANSWER:
Interrelationships among the different nutritional types.
Example: Phototrophs, such as algae and plants, are the producers of food and oxygen for
chemoheterotrophs, such as animals.
Define metabolism - ANSWER: all the chemical reactions that occur in a cell
Define metabolic reactions - ANSWER: The chemical reactions that occur in a cell (same as
metabolism)
What are metabolic enzymes - ANSWER: They enhance and regulate metabolic reactions
What are Biologic Catalysts - ANSWER: they are proteins that either cause a particular chemical
reaction to occur or accelerate it e.g., enzymes
Some key facts on enzymes - ANSWER: 1. Enzymes only catalyze one particular chemical reaction.
2. A particular enzyme can only exert its effect on one particular substance, known as the substrate
for that enzyme.
3. The unique 3-dimensional shape of an enzyme enables it to fit the combining site of the substrate
like a key fits into a lock.
4. An enzyme does not become altered during the chemical reaction it catalyzes.
What are Endoenzymes - ANSWER: Endoenzymes are enzymes produced within a cell that remain
within the cell to catalyze reactions.
Give example of an endoenzyme - ANSWER: digestive enzymes within phagocytes
What are Exoenzymes - ANSWER: Exoenzymes are produced within a cell and then released outside of
the cell to catalyze extracellular reactions.
Give example of an Exoenzymes - ANSWER: cellulase and pectinase, which are secreted by
saprophytic fungi to break down cellulose and pectin, respectively
Give two examples of metabolic enzymes - ANSWER: Hydrolases and polymerases
Many factors affect the efficiency or effectiveness of enzymes. True or False - ANSWER: True
Enzymes function best under optimum conditions. True or False - ANSWER: True
List factors responsible for efficiency or effectiveness of enzymes - ANSWER: 1. pH - extreme acidity
for example
2. Temperature - heat can denature enzymes by breaking bonds
3. Concentration of enzyme and/or substrate - may be too high or too low
