considered a macromolecule. ✔✔False
True or False: Biomolecules can have only two functional groups. ✔✔False
True or False: The following functional group is an alcohol. ✔✔False
True or False: In a eukaryotic cell, the organelles called peroxisomes serve the purpose of
digesting macromolecules. ✔✔False
True or False: Carbon dioxide has a linear molecular shape AND has a bond angle of 109.5
degrees. ✔✔False
Of the following, ____________ is not a property of carbon. ✔✔possessing five valence
electrons
Which of the following is an element not typically found in living organisms? ✔✔He
_____________ is a functional group found in carbohydrates. ✔✔Alcohols
The following functional group is an example of _________. ✔✔Ketone
A ___________ is a chemical formula that does NOT show the C-H and C-C bonds.
✔✔Condensed formula
A collection of two or more macromolecules uniting is called a _______. ✔✔Supramolecular
complex
An organic compound with this structure, C=C, contains a ________ functional group.
✔✔Alkene
Scientists refer to ________ as the "super glue" of the chemistry. ✔✔C
What molecule is most important for energy storage in cells? ✔✔ATP
What would be the approximate size of a human cell? ✔✔12 μm
For propane, there ________ carbon and ________hydrogen atoms. ✔✔3, 8
For an organic compound, which structure is the most efficient to draw? ✔✔Line bond
When writing an organic functional group, scientists often write an "R" as part of the structure.
What does the R indicate? ✔✔Rest of the molecule
According to the module, the study of Non-carbon compounds is referred ____. ✔✔Inorganic
chemistry
Which of the following is not a functional group discussed in this module? ✔✔All of these were
discussed.
Which number would be closest to the approximate number of ribosomes in an E. coli cell?
✔✔25,000
Which of the following would most likely have a cell wall? ✔✔Marigold flower cells
Eukaryotes have molecules that provide protective structural. This network is called the
_____________. ✔✔Cytoskeleton
The molecule linked to the medical condition of gout is __________. ✔✔Uric acid
About how many different elements are found in living organisms? ✔✔30
(Short response) Explain the common similarity in all prokaryotic and eukaryotic cells. Give a
brief explanation of the similarity. ✔✔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) 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. ✔✔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.
(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. ✔✔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) How does organic chemistry differ from inorganic chemistry? ✔✔Organic
chemistry is the study of the carbon-based compounds. Inorganic chemistry is the study of all
other elements, but carbon.
(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?
✔✔Biochemists also study the structure and function of biomolecules and the chemical reactions
of organisms.
