,CHAPTER 1: THE CHEMICAL FOUNDATIONS OF BIOCHEMISTRY
This chapter explores the fundamental chemical principles underlying
biochemistry, including atomic structure, chemical bonds, thermodynamics, and
molecular interactions. Emphasis is placed on the properties of water, pH and
buffering systems, and the behavior of ions and small molecules. Nurses must
understand these principles to interpret lab results, manage electrolytes, and
apply biochemical knowledge to clinical decision-making.
1. Which subatomic particle has a positive charge?
A. Electron
B. Neutron
C. Proton
D. Positron
- CORRECT ANSWER - : C
Rationale: Protons carry a positive charge; electrons are negative and
neutrons are neutral. Positrons are antimatter counterparts of electrons.
2. Water’s ability to form hydrogen bonds primarily contributes to which
property?
A. High viscosity
B. High heat capacity
C. Low polarity
D. Lack of cohesion
- CORRECT ANSWER - : B
Rationale: Hydrogen bonding in water allows it to absorb and retain heat,
contributing to thermal stability essential for biochemical reactions.
3. Which bond is strongest in stabilizing protein tertiary structure?
A. Hydrogen bond
B. Ionic bond
, C. Covalent bond
D. Van der Waals interactions
- CORRECT ANSWER - : C
Rationale: Covalent bonds, including disulfide bridges, are stronger than
noncovalent interactions and provide significant structural stability.
4. pH measures:
A. Hydrogen ion concentration
B. Hydroxide ion concentration
C. Sodium ion concentration
D. Proton acceptor concentration
- CORRECT ANSWER - : A
Rationale: pH quantifies the hydrogen ion (H⁺) concentration, directly
influencing enzymatic activity and cellular function.
5. Which molecule acts as a universal solvent in biological systems?
A. Ethanol
B. Water
C. Methane
D. Chloroform
- CORRECT ANSWER - : B
Rationale: Water’s polarity and hydrogen bonding allow it to dissolve a
wide range of solutes, critical for biochemical reactions.
6. An ionic bond forms due to:
A. Sharing of electrons
B. Transfer of electrons
C. Hydrogen sharing
D. van der Waals forces
- CORRECT ANSWER - : B
