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 - ANSWER -red algae cells
Eukaryotes have molecules that provide a protective structure. This network,
which is found in all eukaryotes, is called the ___. - ANSWER -cytoskeleton
What is the molecule responsible for gout? - ANSWER -uric acid
About how many different elements are found in living organisms? - ANSWER -
30
Explain the common similarity between prokaryotic and eukaryotic cells in at
least 2 sentences. - 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 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. - ANSWER -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. -
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.
What is the definition of inorganic chemistry? How does it different from organic
chemistry - ANSWER -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? -
ANSWER -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. - ANSWER -false
carbon = superglue of the world
T/F: Small elements, such as nitrogen, are common in biomolecules. - ANSWER -
true
Small elements that are common in biomolecules: - ANSWER -CHOPS N:
- carbon
- hydrogen
- oxygen
- phosphorous
- sulfur
- nitrogen
T/F: The time it takes for a compound to flow through a metabolic pathway is
called the flux. - ANSWER -true
