Statement about Muscle Contraction correct?

Postby saryanki » Mon Jan 30, 2012 1:54 pm

"Ca2+ activates Ca-dependent protein kinases that activates to interact with thin filaments."
Is this statement correct? What exactly is the protein kinases then?

What exactly is the definition of "heteronymous innervation"? I found no clear answer on the web.
I read this next to a picture of the innvervation of the strech reflex. Does it mean that not only one but several muscles are innervated?

Thank you very much for your help!

Kinase is an enzyme phosphorylating something. Protein kinase phosphorylates proteins.

Cis or trans? That's what matters.
