Question

Which protein stores oxygen within a skeletal muscle cell?

Answer 1

Myofibrillar proteins

Muscle structures and muscle cells grouped into muscle cells contain myofibrils. The myofibrils are composed of actin and myosin. Actin and myosin are important for muscle fiber structure. They are the most abundant protein muscles, and are directly involved in the ability of muscles to contract and relax.
