Which cell organelle is associated with muscle contraction by release and uptake of $C{a}^{2+}$ ions?

• A. Golgi apparatus
• B. RER
• C. Sarcoplasmic reticulum
• D. Lysosome

SER is associated with muscle contraction by release and uptake of Ca ions because SER functions as the packaging structure which stores the Ca ions until its release.

So, the correct option is 'SER'.
