White meat contains less syoglobin than red meat. Red meat contains more ( slow-twitch / fast-twitch) muscles than white meat do
Nesterboy [21]

Answer:

Slow-twitch

Explanation:

Red meat is rich in slow-twitch muscle fibers. The slow-twitch muscle fibers are rich in myoglobin and blood capillaries. They also have many large mitochondria to generate ATP by aerobic respiration.

These fibers are slow-twitch fibers as the ATPase in myosin head carries out the hydrolysis of ATP at a slower rate causing a slower contraction cycle.

Slow-twitch fibers appear red due to a large amount of myoglobin and a rich network of blood vessels. They are capable of prolonged contractions and are fatigue resistant.
