CHEM 210 - BIOCHEMISTRY - MODULE1 QUESTIONS AND ANSWERS WITH
SOLUTIONS 2024
What do Biochemists study? - ANSWER 1. 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 - ANSWER True.
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? - ANSWER 180 degrees
What is the bond angle of a Trigonal Planar? - ANSWER 120 degrees
What is the bond angle of a Trigonal Pyramidal? - ANSWER 107.5 degrees
what is the bond angle of Tetrahedral? - ANSWER 109.5 degrees
What is carbon referred to in the chemical world? - ANSWER The superglue
What does organic chemistry study? - ANSWER Focuses on the chemical and physical properties of
carbon compounds
What does inorganic chemistry study? - ANSWER The field dealing with metals, minerals, and other non-
organic compounds
How many bonds can a Carbon form? - ANSWER 4! Due to having 4 valence electrons
, What is a long chain of carbons called? - ANSWER Polymers
What is a cyclic compound? - ANSWER Carbons joined together in a closed chain
What are carbon compounds called? - ANSWER Alkanes
Condensed structures give a better idea of a molecules structure, compared to chemical formula. T or F -
ANSWER T
Structural formula gives an even better idea of a molecules structure, compared to chemical formula -
ANSWER T
Advantage of cyclic carbon compounds - ANSWER They 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 -
ANSWER T
Line-bond Drawing - ANSWER Most efficient method to show structure, but requires the most
interpretation.
Functional group - ANSWER specific 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? -
ANSWER The structure
Biomolecules - ANSWER Molecules that are part of the cell or molecules that are excreted by cells.
Macromolecules - ANSWER large biomolecules
