Exam Questions and Correct
Answers | New Update
A ___ is a chemical formula that shows how the atoms of a molecule are
bonded to one another. - ANSWER ✔✔Kekule' structure
A _____ is a chemical formula that does NOT show the C-H and C-C
bonds. - ANSWER ✔✔condensed formula
A collection of two or more macromolecules uniting is called a ___. -
ANSWER ✔✔supramolecular complex
,A fibrous protein is an example of a protein ___. - ANSWER
✔✔conformation
A group of molecules form a clathrate. What is a clathrate and why does
it form? - 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.

According to the module, the study of carbon compounds is referred to
as ___. - ANSWER ✔✔organic chemistry
An organic compound with this structure, C=C, contains a ___ functional
group. - ANSWER ✔✔alkene
, Any molecule or ion that is necessary for an enzyme's function is called:
- 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? - 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. - 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.
