Indicate which type of muscle is associated with the property in question by using the answer code (options may be used more than once or not at all).
-contraction is triggered as Ca²⁺ physically pulls troponin and tropomyosin from its blocking position over actin's binding sites for the cross bridges

Question

Quizplus · Accepted Answer

This property is associated with both skeletal and cardiac muscle, as they both use Ca²⁺ to trigger the movement of troponin and tropomyosin to expose actin's binding sites for cross-bridge formation. Single-unit smooth muscle, on the other hand, uses a different mechanism for contraction that does not involve troponin-tropomyosin regulation.
