CHEM 210 BIOCHEMISTRY - M1: Exam
Questions & Answers (Grade A+)
What are three ways that biochemists study biological organisms? -
correct answer ✅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? -
correct answer ✅Often referred to as the chemistry of life,
biochemistry asks how the remarkable properties of organisms
relate to their molecules.

Questions & Answers (Grade A+)
Are transition metals commonly found in biological organisms? -
correct answer ✅Yes. They are trace elements in organisms. See
Figure 1.3 for examples.
True or false: Water can make up 85% (by mass) of a living
organism. -
correct answer ✅True. Some plants are made up of 90% water by
mass.
True or false: Large elements tend to make the strongest covalent
bonds. -
correct answer ✅False. Smaller elements tend to make the
strongest bonds due to significant overlap.
Name three bulk elements. Name three trace elements. -
correct answer ✅Bulk elements: 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.
Differentiate between inorganic chemistry and organic chemistry. -
correct answer ✅Organic chemistry is the study of carbon-based
compounds. Inorganic chemistry is the study of all other elements.
