A ___ is a chemical formula that shows how the atoms of
a molecule are bonded to one another. - correct answer -
Kekule' structure
A _____ is a chemical formula that does NOT show the C-H
and C-C bonds. - correct answer - condensed formula
A collection of two or more macromolecules uniting is
called a ___. - correct answer - supramolecular complex
A fibrous protein is an example of a protein ___. - correct
answer - conformation
A group of molecules form a clathrate. What is a clathrate
and why does it form? - correct answer - A clathrate is a
cage structure that forms around a substance that has
been placed in water as a result of the hydrophobic
effect. Water orders itself around the hydrophobic portion
of non-polar regions of a substance to maximize
hydrogen bonds. The formation of this structure occurs
,due to the spontaneous drive of water to bind to itself
through hydrogen bonds.
A particular lipid is liquid at room temperature, so it is
called: - correct answer - oil
A particular lipid is solid at room temperature, so it is
called: - correct answer - fat
About how many different elements are found in living
organisms? - correct answer - 30
According to the module, the study of carbon compounds
is referred to as ___. - correct answer - organic
chemistry
An organic compound with this structure, C=C, contains a
___ functional group. - correct answer - alkene
Any molecule or ion that is necessary for an enzyme's
function is called: - correct answer - cofactor
Biochemists study the communication within and around
organisms. According to the module, what are 2 other
aspects of living organisms that biochemists study? -
, correct answer - 1. The relationship between structure
and function of biomolecules
2. Chemical reactions of organisms (metabolism)
3. Communication within and among organisms
Describe at least 3 properties of carbon the permit it to
be the basis of life. - correct answer - 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.
Eukaryotes have molecules that provide a protective
structure. This network, which is found in all eukaryotes,
is called the ___. - correct answer - cytoskeleton
Explain the common similarity between prokaryotic and
eukaryotic cells in at least 2 sentences. - correct answer
- 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
