How does a myoglobin test rule out a heart attack?
If myoglobin levels have not risen after more than five hours, a heart attack in unlikely.
How is a myoglobin test conducted?
This test requires 5 ml of blood. Collection of the sample takes only a few minutes. A urine myoglobin test requires 1 ml of urine collected into a urine collection cup.
What color tube do you use for a myoglobin test?
red/gray mollted
Why is a myoglobin test useful in diagnosing heart attacks?
It is the first marker to rise after chest pain begins. Myoglobin levels rise within two to three hours, and sometimes as early as 30 minutes.
How myoglobin is Distributed in cardiac disorders?
myoglobin
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.
What the primary structure of myoglobin?

What is nitric oxide myoglobin?
When myoglobin is reduced by nitric oxide through the curing process.
What is the difference between haemoglobin and myoglobin?
in myoglobin, the molecules are compacted but in haemoglobin, the molecule formed by 4 subunits which are identical in pairs. its 4 times larger than myoglobin.
Is myoglobin an enzyme?
No.
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.
One advantage hemoglobin has over myoglobin as a respiratory pigment is that?
Cooperative binding. Hemoglobin can load and unload oxygen better than myoglobin. So it is kore sensitive to changes in the environment, vs. Myoglobin
