Answer:
The function of myoglobin is to carry oxygen in the blood and stores oxygen.
Step-by-step explanation:
Myoglobin is a sarcoplasmic protein that stores oxygen in the muscle tissues of vertebrates, it is especially important in aquatic mammals, which are submerged at great depths, these need to remain without breathing for long periods of time, so in their muscles there is a large amount of myoglobin that supplies oxygen during this time. In addition, myoglobin captures oxygen from the blood and facilitates the diffusion from the capillaries into the cells (mitochondria), which is limited by the low solubility of oxygen in aqueous solutions, in order to feed the respiratory chain.
