Question

To generate tension in a muscle, a myosin molecule pulls on an actin filament with a force of 1.50 µN. if the actin filament moves at 3.56 nm/s, what is the power output P of this molecular motor? Use prefixes to express your answer

Answer 1

Gives

Force(F)=$1.50\mu N$

Velocity (v)=$3.56nm/sec$

Power

$P=F.v$

$P=1.50\times10^{-6}\times3.56\times10^{-9}$ W

$P=5.25\times10^{-15}W$
