BIOCHEMISTRY MODULE EXAM 1 QUESTIONS
AND ANSWERS WITH ACCURATE
RATIONALES(PASSED
_____________ is a functional group found in
carbohydrates. - correct answer - Alcohols
(Short response) Biochemists study the communication
within and among organisms. According to the module,
what are two other aspects of living organisms that
biochemists study? - correct answer - Biochemists also
study the structure and function of biomolecules and the
chemical reactions of organisms.
(Short response) Explain the common similarity in all
prokaryotic and eukaryotic cells. Give a brief explanation
of the similarity. - correct answer - Each cell type has a
plasma membrane that separates life from non-life. The
plasma membrane acts as a barrier to most molecules
but does have proteins that permit select molecules to
cross via proteins (transporters).
(Short response) How does organic chemistry differ from
inorganic chemistry? - correct answer - Organic
chemistry is the study of the carbon-based compounds.
, Inorganic chemistry is the study of all other elements, but
carbon.
(Short response) What element is the basis for life?
Describe at least two properties of this element that
permit it to serve the basis for life. - correct answer - 1.
Carbon can form strong covalent bonds with a variety of
different elements. 2. Carbon can form double and triple
bonds with other carbon atoms and other elements (N
and o).
(Short response) Would scientists be more likely to find an
element such as O in a biomolecule, or W? Explain which
she would more likely find in biological molecule and give
specific physical/chemical properties. - correct answer -
She would more likely find O. Smaller elements are
preferred. Smaller elements with smaller atomic shells
are favored because they can form stable covalent bonds,
allowing cells to form, hair to grow, and skin to protect
against abrasion.
A ___________ is a chemical formula that does NOT show
the C-H and C-C bonds. - correct answer - Condensed
formula
