CHEM 210 - BIOCHEMISTRY - MODULE 1 EXAM QUESTIONS & ANSWERS | 100% VERIFIED SOLUTIONS |QUESTIONS WITH CORRECT
ANSWERS 2026 LATEST UPDATE!!
What do Biochemists study? ✔️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 ✔️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? ✔️180 degrees
What is the bond angle of a Trigonal Planar? ✔️120 degrees
What is the bond angle of a Trigonal Pyramidal? ✔️107.5 degrees
what is the bond angle of Tetrahedral? ✔️109.5 degrees
What is carbon referred to in the chemical world? ✔️The superglue
What does organic chemistry study? ✔️Focuses on the chemical and physical properties of carbon compounds
What does inorganic chemistry study? ✔️The field dealing with metals, minerals, and other non-organic compounds
How many bonds can a Carbon form? ✔️4! Due to having 4 valence electrons
What is a long chain of carbons called? ✔️Polymers
What is a cyclic compound? ✔️Carbons joined together in a closed chain
What are carbon compounds called? ✔️Alkanes
Condensed structures give a better idea of a molecules structure, compared to chemical formula. T or F ✔️T
Structural formula gives an even better idea of a molecules structure, compared to chemical formula ✔️T
Advantage of cyclic carbon compounds ✔️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 ✔️T
Line-bond Drawing ✔️Most efficient method to show structure, but requires the most interpretation.
Functional group ✔️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? ✔️The structure
Biomolecules ✔️Molecules that are part of the cell or molecules that are excreted by cells.
Macromolecules ✔️large biomolecules
Molecular mass of a Macromolecule ✔️5,000 g/mol or greater
What are daltons used for? ✔️Larger molecules use Daltons for mass. 1 Da = 1 g/mol
Larger molecules develop more complex structures. T or F ✔️T
What is 25,000 Da in Kilodaltons ✔️25 kDa
Monomers ✔️Single, smallest building block used to build macromolecules.
What is the monomer of DNA? Of proteins? Of carbohydrates? ✔️Nucleotide; Amino Acids; Sugar molecule
Supramolecular Complexes ✔️A complex of two or more macromolecules that routinely interact to function in the cell
