Question 15 • 2026-2027 EDGE Human Anatomy and Physiology A

Some individuals have a condition in which their bodies are unable to properly produce the protein myosin. What is one likely effect of this condition?

Answer
A
muscular weakness
B
hardened ligaments
C
decreased nutrient absorption
D
build up of urine in the kidneys

Myosin is a protein that helps muscles contract by interacting with actin. If the body cannot produce enough functional myosin, muscle contraction is impaired, which can cause muscular weakness. The other choices are not direct effects of impaired muscle proteins.
