Dantrolene is the only drug available to treat malignant hyperthermia. It works by inhibiting calciu channels of the terminal cisterns of the sarcoplasmic reticulum. Explain how this inhibition helps t terminate skeletal muscle contraction.

a. what is the role of ATP in cross-bridge cycling?
Answer- ATP binds to myosin in the cross-bridging cycle, which causes the myosin to move to a high energy state which releases the myosin head from the actin's active site.
b. what is the role of ATP in generating resting membrane potential?
Answer- resting membrane potential is maintained by the Na+/K+-ATPase (sodium-potassium pump) which transports 2 potassium ions inside the cell and 3 sodium ions outside the cell. One ATP is hydrolyzed to conduct this pump.
c. what is the role of ATP in maintaining calcium concentration gradients?
Answer- calcium is actively pumped back into the sarcoplasmic reticulum to terminate the contraction and relax the skeletal muscle. For every Ca2+ (calcium ion) transported one ATP molecule is hydrolyzed.
