The oxygen-binding. function of myoglobin, in situ in the bundles of muscle. fibers, was abolished by chemical treatment, and the contribu-. tion of myoglobin toward the oxygen uptake of the muscle fiber. bundles was estimated from the difference in the steady state.

The more myoglobin the muscles contain, the darker the muscle. Scientists often refer to these active muscles as slow-twitch fibers.
