BIOCHEMISTRY
Prepare for the CHEM 210 Biochemistry Modules 1–8 and Final Exam –
Portage Learning with practice questions covering biomolecules,
enzymes, metabolism, proteins, carbohydrates, lipids, nucleic acids,
and biochemical pathways. This study guide helps reinforce essential
biochemistry concepts and supports effective exam preparation
throughout the course. Designed to improve scientific understanding
and boost confidence in biochemistry coursework and assessments.
Suitable for chemistry, biology, nursing, and healthcare students.
MULTIPLE CHOICE.
MODULE 1: Foundations of Biochemistry & Water
Q1. What is the monomer of a protein?
A: Amino acid
Rationale: Proteins are polymers made of amino acid monomers linked by peptide
bonds.
Q2. Which weak interaction is most responsible for the high specific heat of water?
A: Hydrogen bonding
Rationale: Hydrogen bonds resist temperature changes by absorbing heat to break
bonds.
Q3. Calculate the pH of a solution with [H⁺] = 1 × 10⁻⁹ M.
A: 9
Rationale: pH = –log[H⁺] = –log(10⁻⁹) = 9.

Q4. A solution has pH 5.3. What is its [H⁺]?
A: 5.01 × 10⁻⁶ M
Rationale: [H⁺] = 10⁻⁵·³ = 5.01 × 10⁻⁶ M.
Q5. Which buffer system is primary in human blood?
A: Bicarbonate (H₂CO₃/HCO₃⁻)
Rationale: Maintains blood pH near 7.4 via equilibrium with CO₂.
