Due to the presence of which pigment skeletal muscles are categorised in to red and white muscles?
A. Sarcoplasmic
B. Myoglobin
C. Myosin
D. None of the above
Answers
Myoglobin
On the basis of the presence or absence of a red pigment called myoglobin
Answer: Option (B) Myoglobin
Explanation:
Your striated muscles, which include the cardiac muscles and skeletal muscles (the muscles linked to your bones and tendons), contain the protein known as myoglobin.
Its primary job is to provide oxygen to the cells in your muscles (myocytes).
Your body's cells all require oxygen to function.
They convert the stored energy using oxygen.
Because they are always in use, your heart and skeletal muscles need a lot of oxygen and energy.
Hemoglobin is found in your bloodstream, whereas myoglobin is mostly located in your striated muscles (the types of muscles you consciously move, such as your arm and leg muscles).
Only when there is muscle damage does myoglobin go into the blood.
Your muscle tissues have a reddish tint because of myoglobin, which is similar to haemoglobin.
