Describe how muscles obtain oxygen

WebAerobic respiration, which takes place in the presence of oxygen, evolved after oxygen was added to Earth’s atmosphere. This type of respiration is useful today because the atmosphere is now 21% oxygen. However, … WebRelaxing skeletal muscle fibers, and ultimately, the skeletal muscle, begins with the motor neuron, which stops releasing its chemical signal, ACh, into the synapse at the NMJ. The muscle fiber will repolarize, which closes the gates in the SR where Ca ++ was being released. ATP-driven pumps will move Ca ++ out of the sarcoplasm back into the SR.

Aerobic … WebThe three types of muscle fibers are slow oxidative, fast oxidative and fast glycolytic. Slow oxidative fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue. Fast oxidative fibers use aerobic metabolism to produce ATP but produce higher tension contractions than slow oxidative fibers.
