Myoglobin is a protein in the muscle tissue that stores oxygen. It has a pink colored pigment and is only found in the blood after muscle injury.
Myoglobin stores oxygen in muscles. Hemoglobin stores oxygen in red blood cells.

Does cardiac muscle have more mitochondria and depend less on a continual supply of oxygen than does skeletal muscle?
no
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.
Does that Skeletal muscle produces lactic acid when the body connot supply enough oxygen?
Yes, during periods of intense exercise when oxygen supply is limited, skeletal muscle can produce lactic acid through anaerobic metabolism. This can lead to muscle fatigue and soreness.
Skeletal muscle produces lactic acid when the body cannot supply enough oxygen?
Yes
Do skeletal muscle produce lactic acid when the body cannot supply enough oxygen?
yes
How is oxygen supplied to the skeletal muscle?
Oxygen is transported by red blood cells and is released into tissues as they pass through capillaries in the tissue.
What molecule present primarily within oxidative skeletal muscle cells as an oxygen buffer due to its ability to bind oxygen?
Myoglobin
What must the heart do when muscle cells are oxygen deprived?
When muscle cells are oxygen deprived, the heart must work harder to deliver enough oxygenated blood to the tissues. It may increase heart rate or contractility to compensate for the decreased oxygen supply. If oxygen deprivation persists, it can lead to tissue damage or even a heart attack.
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.
What substance in muscle stores oxygen temporarily?
Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.
When muscle cells are oxygen deprived the heart still pumps, what must the heart cells be able to do?
It must be able to continue aerobic metabolism when skeletal muscle cannot
What substance in muscle seems able to store oxygen temporarily?
Myoglobin is the substance in muscle that can temporarily store oxygen. It is a protein that has a high affinity for oxygen, allowing it to capture and hold oxygen until it is needed for muscle activity.
