living organisms?: He
,8. _____________ is a functional group found in carbohydrates.:
Alcohols
9. The following functional group is an example of _________.:
Ketone
10. A ___________ is a chemical formula that does NOT show the
C-H and C-C bonds.: Condensed formula
11. A collection of two or more macromolecules uniting is called
a _______.: -
Supramolecular complex
12. An organic compound with this structure, C=C, contains a
________ functional group.: Alkene
13. Scientists refer to ________ as the "super glue" of the
chemistry.: C
14. What molecule is most important for energy storage in cells?:
ATP
15. What would be the approximate size of a human cell?: 12 m¼
,16. For propane, there ________ carbon and ________hydrogen
atoms.: 3, 8
17. For an organic compound, which structure is the most
efficient to draw?: Line bond
18. 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
19. According to the module, the study of Non-carbon
compounds is referred
____.: Inorganic chemistry
20. Which of the following is not a functional group discussed in
this module?: All of these were discussed.
21. Which number would be closest to the approximate number of
ribosomes in an E. coli cell?: 25,000
22. Which of the following would most likely have a cell wall?:
Marigold flower cells
, 23. Eukaryotes have molecules that provide protective structural.
This network is called the _____________.: Cytoskeleton
1/2
24. The molecule linked to the medical condition of gout is
__________.: Uric acid
25. About how many different elements are found in living
organisms?: 30 26. (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).
27. (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
