sliding filament theory Flashcards
1
Q
Who created sliding filament theory?
A
Hugh and Andrew Huxley
2
Q
what did they hypothesize?
A
1) That muscles contract and is due to actin sliding over myosin within the muscle fiber which is the shortening of the sarcomeres
2) the role of actin and myosin which are the primary proteins responsible for the contraction
3) They preposed the idea of actin and myosin forming a crossbridge (myosin heads attach produce force to pull ) as well as breaking them by detachment of the myosin head
4) concluded that sarcomeres shorten and
3
Q
define sliding filament theory ?
A
It is the interaction between actin and myosin where myosin heads bind to open sites on actin creating a force to pull the fibers together
