Options

  1. AWhat is the function of the myosin head?
  2. BWhat is the function of the myosin head?
  3. CWhat is the function of the myosin head?
  4. DWhat is the function of the myosin head?

Correct answer

C. What is the function of the myosin head?

Step-by-step solution

Here, E=I(R+r)⇒E=IR+IrE=I(R+r) \Rightarrow E=I R+I r and E=V+IrE=V+ErR+rV=E−ER+r\timesry=c−1x\begin{aligned}& E=V+I r \\ & E=V+\frac{E r}{R+r}\\ & V=E-\frac{E}{R+r} \timesr \\ & y=c-\frac{1}{x} \end{aligned}This equation represents option (3).
