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.
The bright red color of skeletal muscle is due mainly to its?
Myoglobin-myoglobin stores oxygen from red blood cells, which are red. The reason myoglobin stores oxygen (if you wanna know) is to have it available when there's muscle activity.
What molecule holds onto oxygen in blood cells?
Generally, the energy is stored in ATP molecules. This molecule however, is not specific to muscle cells. It is present in all calls where there is a requirement for energy.
What is myoglobulinemia?
You have a myoglobin, an oxygen storage molecule akin to haemoglobin, in the blood. This could be due to the muscle trauma or ischaemia leading to death and breakdown. Myoglobin is toxic to kidney nephrons.
What is myoglobine?
Myoglobin is an iron- and oxygen-binding protein found in the muscle tissue of vertebrates in general and in almost all mammals. It is related to hemoglobin, which is the iron- and oxygen-binding protein in blood, specifically in the red blood cells. The only time myoglobin is found in the bloodstream is when it is released following muscle injury. It is an abnormal finding, and can be diagnostically relevant when found in blood. For full information about myoglobin see the related link below.
What is the iron containing protein that is found in red blood cells and carries oxygen from the lungs?
The iron-containing protein found in red blood cells that carries oxygen is called hemoglobin.
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 is main constituent of blood?
Plasma and water.
Which blood constituent makes up more of the volume of blood?
Plasma
What protein inside red blood cells binds oxygen?
Hemoglobin
How can the oxygen store in myoglobin be replaced after use?
Myoglobin has a very high affinity for oxygen, meaning it binds it very strongly. At very low oxygen concentrations in the cell, myoglobin releases its oxygen, despite the high affinity, simply because there are too few oxygen molecules around to rebind to the myoglobin when they are released naturally from the myoglobin (which usually occurs anyway). Once the oxygen concentration increases again, returning to normal, oxygen molecules will collide with myoglobin. The myoglobin, with its high oxygen affinity, will strongly bind any oxygen that meets it, replenishing myoglobin's oxygen storage very quickly. As myoglobin's affinity for oxygen is stronger the haemoglobin's, it will 'steal' oxygen from haemoglobin in the blood very easily, replacing its bound oxygen. This binding system serves to release oxygen when it is needed if blood oxygen levels are reduced (due to high levels of exercise), but replenishes the supply when oxygen levels begin to rise again.
