Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The compound or pigment acting as an oxygen store in skeletal muscles is-
A
Myoglobin
B
Haemoglobin
C
Myokinase or ATP
D
Cytochrome
Explanation: 

Detailed explanation-1: -Thus, the correct answer is ‘Myoglobin. ‘

Detailed explanation-2: -Myoglobin is a red-colored oxygen-containing pigment found in muscle. It’s related to the pigment hemoglobin, which stores oxygen in blood cells.

Detailed explanation-3: -Introduction. Heart and skeletal muscle myoglobin (Mb) can serve as an oxygen store during times of restricted blood perfusion or apnoea phases.

Detailed explanation-4: -Myoglobin (Mb) is an iron-containing heme protein that is present predominantly in the sarcoplasm of skeletal and cardiac muscles. Due to the presence of heme moiety, myoglobin serves as a carrier and store for oxygen in muscle cells of the body. Myoglobin has more affinity for oxygen as compared to hemoglobin.

Detailed explanation-5: -Myoglobin is a protein that’s found in your striated muscles, which includes skeletal muscles (the muscles attached to your bones and tendons) and heart muscles. Its main function is to supply oxygen to the cells in your muscles (myocytes).
