Myoglobin is found in vertebrate muscle cells and is a water-soluble globular protein. Muscle cells, when put into action, can quickly require a large amount of oxygen for respiration due to their energy requirements. Therefore, muscle cells use myoglobin to accelerate oxygen diffusion and act as localized oxygen reserves for times of intense respiration. Myoglobin also stores the required amount of oxygen and makes it available for the muscle cell mitochondria.
