_____________ is a functional group found in carbohydrates. -
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 biochemist’s study? - ANSWER-In the
module, biochemists also study the structure and function of
biomolecules and the chemical reactions of organisms.
(Short response) Describe at least three properties of carbon that
permit it to be the basis of life. - ANSWER-1. Carbon can form strong
covalent bonds with a variety of different elements.
2. Besides, carbon can form double and triple bonds with other
carbon atoms and other elements (N and O).
3. Carbon can form long chains by forming numerous carbon-carbon
bonds; we call these large molecules polymer.
, 4. Lastly, carbon can form cyclic structures, which are also called ring
compounds.
(Short response) Explain the common similarity in all prokaryotic and
eukaryotic cells. Explain the similarity in at least two sentences. -
ANSWER-The fundamental similarity is that 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). The
plasma membrane permits the cell to have a different composition of
molecules inside the cell than out and defines a space for life to occur.
(Short response) What the definition of inorganic chemistry? How
does it differ from organic chemistry? - ANSWER-Inorganic chemistry
is the study of all other elements, but carbon. Organic chemistry is the
study of carbon-based compounds both in living and non-living
organisms. There is no need to have separate sub-disciples for organic
and inorganic chemistry, but for historical and organizational reasons,
the difference exists.
(Short response) Would a scientist be more likely to find an element
such as O in a biomolecule, or W? Explain which she would more likely
find in a biological molecule and give specific physical/chemical
properties. - ANSWER-She would more likely find O. Smaller elements
are preferred. In the case of O, it is found in water, so it would be
highly concentrated. Smaller elements with smaller atomic shells are
favored because they can form stable covalent bonds. Strong bonds
form by significant overlap of atoms, such as carbon and hydrogen
permitting them to share electrons. The bond that forms require a
substantial amount of energy to break, which allows the bonds to
