QUESTIONS AND ANSWERS SURE A+
✔✔According to the module, the study of carbon compounds is referred to as ___. -
✔✔organic chemistry
✔✔The ___ functional group was NOT discuss in this module.
alcohol
amine
aromatic
thiol
all of these were discussed - ✔✔all of these were discussed
✔✔Which number would be closest to the approximate number of ribosomes in an E.
coli cell?
9
38
400
1,500
26,000 - ✔✔26,000
✔✔Which of the following would most likely have a cell wall?
monkey cells
snake cells
red algae cells
human red blood cells
all of the above - ✔✔red algae cells
, ✔✔Eukaryotes have molecules that provide a protective structure. This network, which
is found in all eukaryotes, is called the ___. - ✔✔cytoskeleton
✔✔What is the molecule responsible for gout? - ✔✔uric acid
✔✔About how many different elements are found in living organisms? - ✔✔30
✔✔Explain the common similarity between prokaryotic and eukaryotic cells in at least 2
sentences. - ✔✔The fundamental similarity between prokaryotic and eukaryotic cells is
the presence of a plasma membrane. This structure separates life from non-life. It acts
as a barrier to the surrounding environment, but contains proteins that permit select
molecules to enter and exit the cell.
✔✔Would a scientist be more likely to find an element such as O in a biomolecule or
W? Explain which they would more likely find and give specific physical/chemical
properties. - ✔✔A scientists would be more likely to find an element such as O in a
biomolecule. Larger elements such as W tend to form ionic bonds, while smaller
elements like O tend to form more stable covalent bonds. Therefore, elements such as
O are more favored by biomolecules because they tend to form stronger bonds by
sharing electrons and forming significant overlap with other elements. As a result, these
stronger bonds require a substantial amount of energy to break them and allows the
bonds to withstand insults, such as thermal and mechanical stress.
✔✔Describe at least 3 properties of carbon the permit it to be the basis of life. - ✔✔1.
Carbon can form strong covalent bonds with a variety of different elements.
2. Carbon can also form double and triple bonds with other carbons atoms as well as
with other elements, such as nitrogen and oxygen.
3. Carbon can form long chains through bonding with other carbons to create long
polymers.
4. Carbon can also form cyclic structures, also referred to as ring compounds.
✔✔What is the definition of inorganic chemistry? How does it different from organic
chemistry - ✔✔Inorganic chemistry is the study of minerals, metals, and other non-
carbon compounds.
Organic chemistry is the study of the chemical and physical properties of carbon.
✔✔Biochemists study the communication within and around organisms. According to
the module, what are 2 other aspects of living organisms that biochemists study? -
✔✔1. The relationship between structure and function of biomolecules
2. Chemical reactions of organisms (metabolism)
3. Communication within and among organisms
✔✔T/F: Hydrogen is called the superglue of the chemical world. - ✔✔false
