myosin head binds to ATP
cross bridge formation
ATP becomes hydrolized
cross bridge formation
ATP turns into ADP and phosphate group
cross bridge formation
ADP and phosphate groups stays on myosin head
cross bridge formation
allows myosin head to bind to actin
cross bridge formation
cross bridge formation:
myosin head binds to…
ATP
cross bridge formation:
ATP becomes …
hydrolized
cross bridge formation:
ATP turns into….
ADP and phosphate group
cross bridge formation:
ultimately allows myosin head to bind to…
actin
myosin head releases phosphate group and ADP
power stroke
causes head to bend backwards motion
power stroke
drags thin filaments towards center of sarcomere
power stroke
power stroke:
myosin head …
releases phosphate group and ADP
power stroke:
myosin head ….
bends in backwards motion
power stroke:
drags….
thin filaments towwards center of sarcomere
new ATP binds to myosin head
bridge detachment
head detaches from actin
bridge detachment
without ATP myosin head doesnt know if they can detach from actin
bridge detachment
bridge detachment:
New ATP binds to…
myosin head
bridge detachment:
allows head to …
detach from actin
bridge detachment:
without ATP…
myosin head doesnt know if it can detach from actin or not
