CHEM 210 BIOCHEMISTRY MODULES 1 TO 8
FINAL PAPER 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ Luciferin. Answer: light-emitting chemical compound, when acted
upon by a protein, glows in the night as these bugs move
◉ Three things biochemists study. Answer: 1) the relationship between
structure and function of biomolecules, 2) chemical reactions of
organisms (metabolism), and 3) communication within and among
organisms
◉ luciferase. Answer: protein (enzyme) that regulates chemical reaction
of light production via luciferin
◉ bulk elements. Answer: carbon, oxygen, nitrogen, sulfur, and
hydrogen
◉ metal elements crucial for life. Answer: magnesium, chromium, and
iron
, ◉ water bond angle. Answer: 104.5
◉ trigonal pyramidal angle. Answer: 107.5
◉ tetrahedral angle. Answer: 109.5
◉ organic chemistry. Answer: branch of study focuses on the chemical
and physical properties of carbon compounds
◉ polymers. Answer: long chains of carbons
◉ cyclic compounds. Answer: atoms also join together in a closed chain.
One advantage of cyclic carbon compounds is that they are more
restricted in their movements and orientation—a property that is
advantageous for building structures and maintaining shape
◉ Kekule Structure. Answer: structural formula. highlights the
connectivity of atoms because it provides more detail. The structure
formula provides the most detail, but it also takes up more space
◉ functional group. Answer: a specific arrangement of atoms that define
the chemistry of the molecule and control the properties of the
compound
