Comprehensive Test Bank for “Lehninger Principles of Biochemistry, 8th
Edition”
Chapter 1: The Foundations of Biochemistry
Multiple Choice Questions (MCQs)
1. Which of the following is a characteristic of living organisms? a) Ability to
reproduce b) Inability to respond to stimuli c) Lack of metabolism d) Static internal
environment
o Correct answer: a)
2. What is the primary role of enzymes in biochemical reactions? a) To act as
reactants b) To increase the activation energy c) To speed up reactions d) To be
consumed in the reaction
o Correct answer: c)
Short Answer Questions (SAQs)
1. Explain the concept of homeostasis in living organisms.
o Answer: Homeostasis is the maintenance of a stable internal environment in an
organism, allowing it to function optimally despite external changes.
2. Describe the role of water in biochemical reactions.
o Answer: Water acts as a solvent, participates in hydrolysis and dehydration
reactions, and helps maintain the structure and function of biomolecules.
Essay Questions
1. Discuss the importance of carbon in biological molecules.
o Answer: Carbon is essential in biological molecules due to its ability to form four
covalent bonds, creating diverse and complex structures necessary for life.
2. Explain the role of ATP in cellular metabolism.
o Answer: ATP serves as the primary energy currency in cells, providing energy for
various biochemical processes, including muscle contraction, active transport, and
biosynthesis.
True/False Questions
1. All living organisms are composed of cells.
o True
2. Enzymes are consumed in the reactions they catalyze.
o False
Matching or Fill-in-the-Blank Questions
1. ________ is the molecule that stores genetic information in cells.
o Answer: DNA
,2. Match the following:
o Enzyme: Catalyzes biochemical reactions
o Lipid: Forms cell membranes
o Carbohydrate: Provides energy
o Nucleic Acid: Stores genetic information
Figures and Diagrams (optional)
1. Label the parts of a typical eukaryotic cell (diagram provided).
Chapter 2: Water
Multiple Choice Questions (MCQs)
1. What property of water allows it to dissolve many substances? a) High specific
heat b) Polarity c) Low density d) Non-polarity
o Correct answer: b)
2. Which of the following best describes hydrogen bonding in water? a) Covalent
bonds between hydrogen and oxygen b) Ionic bonds between water molecules c)
Weak attractions between the hydrogen of one water molecule and the oxygen of
another d) Strong attractions between hydrogen and carbon
o Correct answer: c)
Short Answer Questions (SAQs)
1. Explain why water has a high specific heat.
o Answer: Water has a high specific heat due to hydrogen bonding, which requires
more energy to break, allowing water to absorb and release heat slowly.
2. Describe the role of water in maintaining cell structure.
o Answer: Water maintains cell structure by providing turgor pressure in plant cells
and contributing to the hydration shell around biomolecules.
Essay Questions
1. Discuss the significance of water’s polarity in biological systems.
o Answer: Water’s polarity allows it to dissolve ionic and polar substances,
facilitating biochemical reactions and transport of nutrients and waste in
organisms.
2. Explain the role of water in acid-base balance in the body.
o Answer: Water acts as a solvent for acids and bases, allowing them to dissociate
and participate in buffering systems that maintain pH balance in the body.
True/False Questions
1. Water is a non-polar molecule.
,o False
2. Hydrogen bonds are responsible for water’s high boiling point.
o True
Matching or Fill-in-the-Blank Questions
1. ________ is the process by which water moves across a semipermeable membrane.
o Answer: Osmosis
2. Match the following:
o Cohesion: Attraction between water molecules
o Adhesion: Attraction between water and other substances
o Solvent: Substance that dissolves solutes
o Solute: Substance dissolved in a solvent
Figures and Diagrams (optional)
1. Label the hydrogen bonds between water molecules in a diagram.

o Answer: Water acts as a solvent, participates in hydrolysis and dehydration
reactions, and helps maintain the structure and function of biomolecules.
3. What is the significance of hydrogen bonding in water?
o Answer: Hydrogen bonding in water leads to its high specific heat, surface
tension, and solvent properties, which are crucial for biological processes.
4. How do enzymes lower the activation energy of biochemical reactions?
o Answer: Enzymes lower activation energy by stabilizing the transition state and
providing an alternative reaction pathway.
5. What is the role of ATP in cellular metabolism?
o Answer: ATP serves as the primary energy currency in cells, providing energy for
various biochemical processes, including muscle contraction, active transport, and
biosynthesis.
