Question

Which of the following is false about slow oxidative skeletal muscle fibers?

a) They are well adapted for endurance
b) They contain large Sarcoplasmic Reticulum
c) They rely on aerobic ATP production
d) They contain a form of myosin with slow ATPase
e) They contain abundant mitochondria

Answer 1

Slow oxidative skeletal muscle fibers are well adapted for endurance and rely on aerobic ATP production. They contain a form of myosin with slow ATPase and abundant mitochondria.

Step-by-step explanation:

Slow oxidative skeletal muscle fibers, also known as slow-twitch fibers, are well adapted for endurance. They rely on aerobic ATP production, which requires oxygen, to sustain contractions over long periods. They contain a form of myosin with slow ATPase, which allows for slower contractile speed. Additionally, they contain abundant mitochondria, which produce ATP through aerobic metabolism.
