Which of the following metal ion plays an important role in muscle contraction?
- A \(\mathrm{Fe}^{2+}\)
- B \(\mathrm{Ca}^{2+}\)
- C \(\mathrm{Au}^{+}\)
- D \(\mathrm{Na}^{+}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Ca}^{2+}\)
Step-by-step Solution
Detailed explanation
In muscle contraction, calcium ions \(\mathrm{Ca}^{2+}\) play an important role by building interactions between proteins, myosin and actin. The \(\mathrm{Ca}^{2+}\) ions bind to the \(C\) portion of actin filament, exposing binding region to which myosin head is attached to in…
