Question

Role of sarcoplasmic reticulum in muscle contraction

Answer 1

Answer:

The sarcoplasmic reticulum is a membrane - bound structure found within muscle cells that is similar to endoplasmic reticulum in other cells . The main function of SR is to store calcium ions . SR is very abundant in skeletal muscle cells and is closely associated with the MYOFIBRILS ( and , therefore, the MYOFILAMENTS) . This as you will see , is a key step in muscle contraction.....

Answer 2

Answer:

Explanation:

But the primary function of the SARCOPLASMIC RETICULUM is to STORE CALCIUM IONS. Sarcoplasmic reticulum is very abundant in skeletal muscle cells and is closely associated with the MYOFIBRILS (and, therefore, the MYOFILAMENTS). ... This, as you will see, is a key step in muscle contraction.
