Assertion: Calmodulin plays an important role in excitation contraction (EC) coupling and the initiation of the cross-bridge cycling in smooth muscle.
Reason: Troponin is not found in the smooth muscles.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
Assertion: Myoglobin needs to have a higher affinity for oxygen than hemoglobin.
Reason: To perform its job, myoglobin must effectively bind any oxygen released from hemoglobin.
