Without the Protein Myosin, What Structures Would Also Be Missing

Question

Without the protein myosin, what structures would also be missing in a muscle?
A) ribosomes
B) mitochondria
C) thin filaments
D) thick filaments

Accepted Answer

Myosin is a component of thick filaments in muscles. Without myosin, the thick filaments would not be able to function properly and muscle contraction would not occur. Ribosomes and mitochondria are not directly involved in muscle contraction, while thin filaments are composed of actin, not myosin.
