What is the role of calcium in contraction?
Calcium binds to the myosin heads to allow myosin heads to bind to the myosin binding sites.
Calcium binds to the tropomyosin to allow myosin heads to bind to the myosin binding sites.
Calcium binds to the troponin to allow myosin heads to bind to the myosin binding sites.
Calcium binds to the tropomyosin to allow actin to bind to the M line.
What is the role of ATP in contraction?
ATP binds to the myosin heads to allow myosin heads to bind to the myosin binding sites.
ATP binds to the tropomyosin to allow myosin heads to bind to the myosin binding sites.
ATP binds to the troponin to allow myosin heads to bind to the myosin binding sites.
ATP binds to the tropomyosin to allow actin to bind to the M line.
Sliding
A neuron sends a message to the muscle fiber to contract.
Calcium binds to troponin. Troponin signals tropomyosin to move out of the way freeing the myosin binding sites.
ATP binds to the myosin heads. Myosin heads bind to myosin binding sites and move actin towards the M line.
Calcium binds to tropomyosin. Tropomyosin signals troponin to move out of the way freeing the myosin binding sites.
ATP binds to the myosin heads. Myosin heads bind to myosin binding sites and move myosin towards the M line.
In order to move, myosin needs....
1 ATP per stroke (one for up and one for down)
2 ATP per stroke (two for up and two for down)
1 Calcium (one for up and one for down)
2 Calcium (two for up and two for down)
In order to move tropomyosin, troponin needs....
1 ATP per stroke
2 ATP per stroke
1 Calcium per troponin
2 Calcium per troponin
