Mod 1 Quiz Question 10
Question 1 Name three bulk elements. Name three trace
What are three ways that biochemists study elements.
biological organisms? Bulk elements (three of these): H, C, N, O, Na, P, S,
1) the relationship between structure and function Cl, K, and Ca
of biomolecules Trace elements: Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn,
2) chemical reactions of organisms (metabolism) Se, Mo, I, and W.
3) communication within and among organisms.
Question 11
Question 2 Differentiate between inorganic chemistry and
What is the definition of biochemistry? organic chemistry.
Often referred to as the chemistry of life, Organic chemistry is the study of carbon-based
biochemistry asks how the remarkable properties compounds. Inorganic chemistry is the study of all
of organisms relate to their molecules. other elements.
Question 3 Question 12
What is another name for firefly? Is H2O an organic molecule? How about CO2?
Lightening bugs C100H202?
Water is not organic; it does not contain carbon.
Question 4 Both CO2and C100H202 are organic compounds.
Is Li an element common in biological organisms?
No Question 13
The next row of Table 1 would be the 6-carbon
Question 5 alkane, hexane. Write out its chemical formula and
What is known as the “medium of life”? condensed formula.
Water chemical formula: C6H14
Condensed formula: CH3CH2CH2CH2CH2CH3
Question 6
What is the bond angle associated with trigonal Question 14
pyramidal shape? On your own paper, draw the Kekule structures and
107.5 degrees line-bond formulas for both butane and hexane.
Question 7
Are transition metals commonly found in biological
organisms?
Yes.
Question 8
True or false: Water can make up 85% (by mass) of
a living organism.
True. Some plants are made up of 90% water by
mass. Question 15
How are the aldehyde and ketone functional
Question 9 groups similar? Different?
True or false: Large elements tend to make the Aldehdyes and ketones both have a carbon double
