Question 2

The essential ion required for muscle contraction, facilitating the interaction between actin and myosin filaments, is:

Accepted Answer

C. Calcium (Ca2+) — Calcium ions (Ca2+) play a pivotal role in muscle contraction. When released from the sarcoplasmic reticulum, Ca2+ binds to troponin, causing a conformational change that moves tropomyosin away from the actin binding sites, thereby allowing myosin heads to attach to actin and initiate the contraction cycle. Sodium and potassium ions are crucial for nerve impulse transmission and muscle action potentials, but not directly for the actin-myosin interaction itself.
