Question 1
A nurse is explaining cellular physiology to a student. Which of the following is an
example of mechanical cellular work performed by human cells?
A. The synthesis of a hormone.
B. The active transport of sodium out of a cell.
C. The contraction of a muscle fiber.
D. The production of ATP.
CORRECT ANSWER: C
RATIONALE: Mechanical work involves physical movement. Muscle contraction, ciliary
beating, and chromosome movement during mitosis are all examples of mechanical
work performed by cells using energy.

Question 2
A nursing student correctly identifies that active transport across a cell membrane is an
example of:
A. Chemical work
B. Mechanical work
C. Transport work
D. Passive diffusion
CORRECT ANSWER: C
RATIONALE: Transport work requires energy to move substances against a
concentration gradient, such as with ion pumps (Na+/K+ ATPase), endocytosis, and
exocytosis.
Question 3
The process of building complex molecules like proteins from simpler ones is best
categorized as which type of cellular work?
A. Mechanical
B. Transport
C. Chemical
D. Kinetic
CORRECT ANSWER: C

RATIONALE: Chemical work, also known as biosynthesis, is the energy-requiring process
of synthesizing cellular components such as proteins, nucleic acids, and lipids from
smaller precursors.
Question 4
A nurse is educating a client with diabetes about glucose. The nurse explains that
glucose (C6H12O6) is a primary energy source and is stored in animal tissues in the form
of:
A. Starch
B. Cellulose
C. Glycogen
D. Triglycerides
CORRECT ANSWER: C
RATIONALE: Animals store excess glucose as glycogen, primarily in the liver and skeletal
muscles. Plants store glucose as starch.
Question 5
A nurse is reviewing cellular metabolism. In a chemical reaction, the starting substances
that undergo change are called:
A. Products
B. Reactants
