Question 15 • PA Human Anatomy & Physiology A 2026-2027 SMITH IC

Which statement best describes a direct result of damage to a phospholipid bilayer?

Answer
A
The balance of ions inside a cell will be disrupted and proteins could leak out because the phospholipid bilayer forms the cell membrane.
B
Energy storage will be disrupted because the phospholipid bilayer is responsible for storing energy in the body.
C
Chemical messages could not be sent to different parts of the body because the phospholipid bilayer forms hormones.
D
A person would be vulnerable to disease because the phospholipid bilayer helps to fight infections in the body.

Explanation

The phospholipid bilayer forms the cell membrane, which controls what enters and leaves a cell. If it is damaged, ions can move across the membrane improperly, and proteins or other cell contents may leak out. The bilayer does not store the body's energy, form hormones, or directly fight infections.
