CHEM 210 - BIOCHEMISTRY -
MODULE 1 EXAM QUESTIONS WITH
VERIFIED ANSWERS
What do Biochemists study? - CORRECT ANSWERS1. The relationship between
structure and function of biomolecules
2. Chemical reactions of organisms
3. Communication within and among organisms
Smaller elements are favored because they can form stable covalent bonds. T or F -
CORRECT ANSWERSTrue. Strong bonds form by significant overlap of atoms, such as
carbon and hydrogen, allowing them to share electrons.
What is the bond angle of a Linear molecule? - CORRECT ANSWERS180 degrees
What is the bond angle of a Trigonal Planar? - CORRECT ANSWERS120 degrees
What is the bond angle of a Trigonal Pyramidal? - CORRECT ANSWERS107.5 degrees
what is the bond angle of Tetrahedral? - CORRECT ANSWERS109.5 degrees
What is carbon referred to in the chemical world? - CORRECT ANSWERSThe
superglue
What does organic chemistry study? - CORRECT ANSWERSFocuses on the chemical
and physical properties of carbon compounds
What does inorganic chemistry study? - CORRECT ANSWERSThe field dealing with
metals, minerals, and other non-organic compounds
How many bonds can a Carbon form? - CORRECT ANSWERS4! Due to having 4
valence electrons
What is a long chain of carbons called? - CORRECT ANSWERSPolymers
What is a cyclic compound? - CORRECT ANSWERSCarbons joined together in a
closed chain
What are carbon compounds called? - CORRECT ANSWERSAlkanes
Condensed structures give a better idea of a molecules structure, compared to chemical
formula. T or F - CORRECT ANSWERST
Structural formula gives an even better idea of a molecules structure, compared to
chemical formula - CORRECT ANSWERST
Advantage of cyclic carbon compounds - CORRECT ANSWERSThey are more
restricted in their movements and orientation - advantageous for building structures and
maintaining shape
Carbon can form double and triple bonds with other carbon atoms or atoms of other
elements. T or F - CORRECT ANSWERST
Line-bond Drawing - CORRECT ANSWERSMost efficient method to show structure, but
requires the most interpretation.
Functional group - CORRECT ANSWERSspecific arrangement of atoms; they define
the chemistry of the molecule and control the properties of the compound.
What dictates the chemical and physical properties of compounds, including
biochemical compounds? - CORRECT ANSWERSThe structure
Biomolecules - CORRECT ANSWERSMolecules that are part of the cell or molecules
that are excreted by cells.
