Question

When pre-rigor fish are frozen, the following ions are released into sarcoplasmic reticulum at high concentration causing thaw rigor

• A. \(Mg^{2+}\)
• B. \(Ca^{2+}\)
• C. \(Na^{+}\)
• D. \(Cl^{-}\)

Hint:

Muscle contraction, relaxation, and post-mortem rigor are biochemically regulated by the intracellular concentration of calcium (\(Ca^{2+}\)) ions.
