Question

the structure that is involved in calcium storage in skeletal muscle is called_______. sarco plasmic reticulum mitochondria intermediate filament network myofibrillar network

Explanation:

The sarcoplasmic reticulum is a specialized endoplasmic reticulum in muscle cells. Its main function in skeletal muscle is to store calcium ions ($Ca^{2+}$). When a muscle is stimulated to contract, the sarcoplasmic reticulum releases $Ca^{2+}$ into the cytoplasm. This $Ca^{2+}$ then binds to troponin, which leads to a conformational change that allows actin - myosin interaction and muscle contraction. Mitochondria are the powerhouses of the cell, responsible for generating ATP through cellular respiration. Intermediate filament networks provide structural support to the cell. The myofibrillar network is related to the contractile machinery of the muscle (composed of actin and myosin filaments), but it is not involved in calcium storage.

Answer:

sarcoplasmic reticulum
