Vedclass · Answer

(A) Muscles contain a red-coloured oxygen-storing pigment called myoglobin. Myoglobin content is high in some muscles,which gives them a reddish appearance; these are called red fibres. Red fibres contain a large number of mitochondria,which utilize the stored oxygen for $ATP$ production,hence they are known as aerobic muscles. Conversely,muscles with a low quantity of myoglobin appear pale or whitish and are called white fibres. White fibres have fewer mitochondria and rely more on anaerobic processes for energy,hence they are known as anaerobic muscles.
