1. If a new biomolecule is discovered that contains both a hydroxyl group and a
carboxyl group, what implications does this have for its reactivity?
The biomolecule will only function as a structural component.
The biomolecule may exhibit diverse chemical reactivity due to the
presence of multiple functional groups.
The biomolecule will be inert and unreactive.
The biomolecule will only react with water.
2. In organic chemistry, what does the 'R' in a functional group represent?
An oxygen atom
A hydrocarbon chain or substituent
A nitrogen atom
A carbon atom
3. Gout is caused by crystals.
ammonia
calcium oxalate
uric acid
cystine
4. If you were to create a structural formula for a complex organic molecule,
what key features would you need to include to ensure clarity?
The molecular weight and boiling point of the compound.
, Only the total number of atoms in the molecule.
The color and physical state of the compound at room temperature.
The arrangement of atoms, types of bonds, and functional groups
present in the molecule.
5. Which of the following is true about the functional groups in
macromolecules?
Functional groups do not affect the properties and functions of
macromolecules
Functional groups are only found in proteins and not in other
macromolecules
Functional groups can change the shape and function of
macromolecules
Functional groups are interchangeable between different types of
macromolecules.
6. Describe how inorganic chemistry is distinct from organic chemistry in terms
of compound composition.
Inorganic chemistry studies only metals, whereas organic chemistry
studies only non-metals.
Inorganic chemistry is concerned with the study of gases, while
organic chemistry studies liquids.
Inorganic chemistry focuses on compounds that generally do not
contain carbon-hydrogen bonds, while organic chemistry is
centered on carbon-containing compounds.
Inorganic chemistry deals with all types of chemical reactions, while
organic chemistry focuses solely on biological reactions.
,7. Eukaryotes have molecules that provide protective structural. This network is
called the _.
Cytosol
Cytoplasm

Cytoskeleton
Both Cell wall and Cytoskeleton
8. The most common functional groups on Carbs, such as glucose (and the one
that participates in polymerization) are:
amino
carboxyl
Hydroxyl
Sulfhydryl
9. An organic compound with this structure, C=C, contains a functional
group.
Alkyne
Alkene
Alcohol
Both B and D
Alkane
10. Carbohydrates may contain the functional groups:
of an aldehyde
, of a ketone
hydroxyl groups
all of the above
11. Describe the significance of the ketone functional group in organic
chemistry.
The ketone functional group is significant because it is a type of
alcohol that contains a hydroxyl group.
The ketone functional group is essential because it is a type of amine
that contains a nitrogen atom.
The ketone functional group is crucial as it is a derivative of carboxylic
acids that contains a carbonyl group.
The ketone functional group is important because it contains a
carbonyl group (C=O) flanked by two carbon atoms, which
influences the reactivity and properties of the molecule.
12. Describe the significance of a cell wall in red algae cells compared to
human red blood cells.
Red algae cells have a cell wall that provides structural support,
while human red blood cells lack a cell wall and are more flexible.
Human red blood cells have a rigid cell wall, while red algae cells do
not.
Both red algae cells and human red blood cells have a cell wall for
protection.
Red algae cells are more flexible than human red blood cells due to
their lack of a cell wall.
13. Which of the following is an element not typically found in living organisms?
