Anaerobic fermentation enables a cell to produce ATP in the absence of oxygen but the ATP yield is very limited and the process produces a toxic end product, lactic acid, which is a major factor in muscle fatigue.
yes
movement or heat
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
Yes, during periods of intense exercise when oxygen supply is limited, skeletal muscle can produce lactic acid through anaerobic metabolism. This can lead to muscle fatigue and soreness.
Yes, because of the short refractory period of skeletal muscle (compared to cardiac muscle), skeletal muscle can be restimulated before the muscle is completely relaxed. If repeated enough times, the contractions fuse together i.e. they become tetanised.
SKELETAL (:
skeletal muscles
Skeletal muscle fibers contain numerous nuclei. This is used to produce large amounts of the enzymes and structural proteins needed for muscle contraction.
