Which of the following are contractile proteins in skeletal muscle?
c. tropomyosin protein
I bandisotropic: reflects light uniformly
A bandanisotropic: scatter light unevenly
Picture far left and far right=zline, bottom left and bottom right= I band, A band is in
between I bands, on top of the a band is the H zone, middle bar is the m line
Middle bottom line is called sarcomere.
Myofibril structure fig 123c &d
Organization of the myofibril protein components
myosin coiled protein molecules that have two important parts ▯ head&tail region
250 myosin molecules join▯think filament
study the structure with the myosin with one lighter be
