Myoglobin is a protein within the muscle tissue which acts as an oxygen carrier.
As a long term effect of exercise. The ability of the muscles to store myoglobin is increased. Because muscles increase their oxidative capacity through regular exercise, the myoglobin stores also increase because they get used to the demands of exercise and work placed upon them so increase stores as they will be needed. The increase in oxidative capacity is achieved by an increase in the number of mitochondria within the muscle cells, an increase in the supply of ATP and an increase in the quantity of enzymes involved in respiration.

What does an increase in myoglobin stores mean?
An increase in myoglobin stores means there is more oxygen-binding protein available in muscle tissues. This can improve the muscles' ability to store and utilize oxygen, leading to better endurance and performance during physical activities.
What compound stored oxygen inside skeletal muscle cells?
keratinThe correct answer is NOT keratin... the correct answer is myoglobin. This is the oxygen-binding pigment in muscle.
Is myoglobin and myoglobulin the same?
No, myoglobin and myoglobulin are not the same. Myoglobin is a protein found in muscle tissues that binds and stores oxygen, while myoglobulin is a misspelling or incorrect term for myoglobin.
What protein stores O2 in tissues?
myoglobin
The bright red color of skeletal muscle is due mainly to its?
rich supply of myoglobin, a protein that stores oxygen in muscle cells. Myoglobin has a deep red color when exposed to oxygen, giving skeletal muscle its distinctive hue.
What in muscle cells increase as a result of exercise?
Muscle cells increase in size (hypertrophy) and in number of mitochondria, which are responsible for producing energy. Additionally, exercise can lead to an increase in the concentration of myoglobin, which helps store and transport oxygen in the muscles.
Muscles contain an oxygen storage pigment called what?
Muscles contain an oxygen storage pigment called myoglobin. Myoglobin helps muscles store and transport oxygen for energy production during exercise.
What is the mass of myoglobin a protein that stores oxygen?
The mass of myoglobin, a protein that stores oxygen in muscle tissues, is approximately 17.8 kDa (kilodaltons). It is a small protein that consists of a single polypeptide chain.
How myoglobin is Distributed in cardiac disorders?
In cardiac disorders, myoglobin levels in the blood may increase due to damage to heart muscle cells. Elevated myoglobin levels can indicate myocardial infarction (heart attack) or other types of cardiac injury. Myoglobin is released into the blood when heart muscle cells are damaged, making it a useful biomarker for detecting and monitoring cardiac disorders.
What is nitric oxide myoglobin?
Nitric oxide myoglobin is a form of myoglobin that can bind to nitric oxide. This interaction helps regulate blood flow by releasing nitric oxide, which acts as a vasodilator to increase blood vessel diameter and improve oxygen delivery to tissues.
What are the changes in muscle with exercise?
Training in increases the vascularization of muscle so that more blood can be delivered to the tissue when active. In addition there is an increase in muscle mass, increased ability for metabolism with more myoglobin and more mitochondria in active tissue.
What does myoglobin do for muscles?
Myoglobin's function is similar to that of hemoglobin, which carries oxygen in red blood cells to various tissues. Myoglobin has even higher affinity for oxygen than hemoglobin and is specific to muscle cells. Myoglobin thus acts as a storage of oxygen, as it holds oxygen inside heart and skeletal muscles.
