What are three ways that biochemists study biological organisms?
Biochemists study 1) the relationship between structure and function of
biomolecules, 2) chemical reactions of organisms (metabolism), and 3)
communication within and among organisms.
What is the definition of biochemistry?
Often referred to as the chemistry of life, biochemistry asks how the
remarkable properties of organisms relate to their molecules.

Are transition metals commonly found in biological organisms?
Yes. They are trace elements in organisms. See Figure 1.3 for examples.

False. Smaller elements tend to make the strongest bonds due
to significant overlap.
Name three bulk elements. Name three trace elements.
Bulk elements (three of these): H, C, N, O, Na, P, S, Cl, K, and Ca
Trace elements: Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Mo, I, and W.
The following statement is incorrect. Rewrite the statement to be correct.
Statement: Organic chemistry is the study of metal compounds, while
inorganic chemistry is the study of carbon compounds.
Organic chemistry is the study of carbon-based compounds,
while inorganic chemistry is the study of all other compounds,
including metals, minerals, and other non-organic compounds.
Is H2O an organic molecule? How about CO2? C100H202?
Water is not organic; it does not contain carbon. Both CO2 and C100H202
are organic compounds.
