Chapter 1–2: Basic Concepts + Chemistry of Life
1. The primary function of the cell membrane is to:
A. Store genetic material
B. Control entry and exit of substances
C. Produce ATP
D. Synthesize proteins
,Answer: B
Rationale: The plasma membrane regulates what enters and leaves the cell, maintaining
homeostasis.
2. Which of the following best describes anatomy?
A. Study of body functions
B. Study of body structure
C. Study of disease
D. Study of tissues only
Answer: B
Rationale: Anatomy focuses on structure, while physiology focuses on function.
3. Which type of bond involves sharing electrons?
A. Ionic bond
B. Hydrogen bond
C. Covalent bond
D. Polar attraction
Answer: C
Rationale: Covalent bonds form when atoms share electrons.
4. Water is considered a polar molecule because:
A. It has no charge
B. It has equal distribution of electrons
C. It has partial positive and negative charges
D. It cannot dissolve substances
Answer: C
Rationale: Oxygen is more electronegative, creating partial charges.

Answer: C
Rationale: Cells are the basic structural and functional units of all living organisms.
6. Which organelle modifies and packages proteins?
A. Ribosome
B. Mitochondria
C. Golgi apparatus
D. Lysosome
Answer: C
Rationale: The Golgi apparatus processes and packages proteins for transport.
7. Passive transport requires:
