Question

You discover a new type of bird (their muscle types are similar to human sorts).  This particular bird’s chest muscles are a very deep red color. Is this muscle more likely to have abundant glycogenor abundant mitochondria, or is there no way to choosebased on the red color of the muscle?

Answer 1

Since, the bird has muscles similar to human sorts, then the red colour chest muscle of a

bird is "pectoralis muscle". Beacuse this skeletal muscle( pectoralis or chest muscle) also

found in the chest of human that moving the arm in an a downward motion, the same is

assists to birds in flying as downstroke movement.

It is also true that the chest muscle(discussed above) has abundant mitochondria & rich in

glycogen because the red skeletal muscle are found in those organs which have to need

continuous energy for function without tiring or fatigue up. This is given by mitochondria

(oxidation) and glycogen(fuel to burn).
