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