Troponin i

... of muscle contraction, the action potential causing a release of Calcium from the SR, followed by the "turning off" of tropomyosin by troponin to expose the active sites on the myosin heads so that they can bind to the actin and initiate contraction, then you know what an incredible ...

Troponin is a serum cardiac marker that is released into the blood in large quantities from the necrotic heart muscle after a heart attack. It is a very good indicator because it remains elevated two weeks after the initial ...

... is available. It's true, though, that a deficit in ATP will cause muscle stiffness because in the ADP-form the myosinheads cant release from the troponin, which is Ca(2+) dependant in making a bindingsite for myosin. (in rigor mortis Ca(2+) will diffuse out of the ER but no ATP is available leading ...
