Hint: Myoglobin is similar to hemoglobin. Diving mammals do have a high amount of Myoglobin in their muscle cells. It is due to the Myoglobin’s capacity to bind oxygen. High amount of myoglobin in muscle cells in an organism allows it to hold breath for a longer period of time.
Complete Solution: In animal muscle cells, especially in heart and skeletal muscles, myoglobin is found. The iron and oxygen binds are a myoglobin protein. In nearly all mammals, myoglobin is present. It is found in vertebrates' skeletal muscle tissue. Myoglobin is hemoglobin-related. The affinity of myoglobin for oxygen is greater than hemoglobin. Myoglobin occurs primarily in humans after muscle injury in the bloodstream. At the time of a heart attack or muscle damage, myoglobin is released into your bloodstream.
Note: In the muscle skeleton of the vertebrates, myoglobin is found. The oxygen affinity of myoglobin is greater than that of hemoglobin. Myoglobin captures oxygen that can be used for energy by muscle cells. Myoglobin is released in the bloodstream, \[2 - 3\] hours after the symptoms of muscle damage. It usually reaches higher concentration in \[8 - 12\] hours.
Additional Information: Mammals such as whales and seals who dives have muscles with particularly high amounts of myoglobin. High amount of myoglobin in muscle cells in an organism allows it to hold breath for a longer period of time. Myoglobin is found in Type I, Type II A, and Type II B muscles. Myoglobin is not found in smooth muscle. Human kidneys filter your blood for myoglobin to be removed by urine from the body. But too much myoglobin can harm the kidneys and can lead to kidney failure.
