If a drug caused a sudden release of large amounts of calcium in skeletal muscle, from which structure would the calcium come?

The correct answer will be option-sarcoplasmic reticulum.

Explanation:

The sarcoplasmic reticulum is the membrane bound endoplasmic reticulum of the muscle cell which stores a large amount of Ca⁺² ions.

The reticulum contains Calsequestrin- a calcium binding protein which binds around 50 Ca⁺² ions to itself and helps store more calcium. These calcium ions are released when the signals through T-tubules are carried to the reticulum which leads to the opening of the calcium channels.

Thus, sarcoplasmic reticulum is the correct answer.

c u c l 2 + 2 n a n o 3 → c u ( n o 3 ) 2 + 2 n a c l

  long weird answer but i hope this works

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
