This signals the muscle fibers to contract.

When the interior of the meat reaches 170° F, hemichrome levels rise, and the myoglobin becomes metmyoglobin, which gives well-done meat its brown-gray shade. White meat is made up of muscles with fibers that are called fast-twitch. " - Slow twitch fibers color
