In reference to biological role, Ca2+ ions are important in

1. triggering the contraction of muscles
2. generating right electrical potential across cell membrane
3. hydrolysis of ATP
4. defence mechanism

Correct answer: triggering the contraction of muscles

Solution

Ca2+ ions play a crucial role in muscle contraction by interacting with proteins like troponin and tropomyosin, which regulate the contraction process.
