Explanation:

Skeletal muscle fibers have a more extensive sarcoplasmic reticulum compared to smooth muscle fibers. The sarcoplasmic reticulum in skeletal muscle is well - developed to store and release calcium ions for rapid and coordinated contraction. In smooth muscle, the sarcoplasmic reticulum is less extensive as the contraction mechanisms are different and often rely more on extracellular calcium.

Answer:

False
