How many actin monomers within an actin filament would a myosin molecule need to ratchet in order to contract a cell by approximately 1 μm? How fast could a non-muscle cell make this contraction compared to a muscle cell if the relative rates of myosin walks on F-actin are 4.5 μm/sec and 0.04 μm/sec for myosin II and I respectively?
Assume an axon has the same characteristics as the class example
except the radius of the axon is 0.005 mm and the membrane
thickness is 20.0 nm. The percentage fractional change in the
concentration of Na+ ions in the axon during one action potential is
%? Record the answer to the nearest one
thousandth.
What is the magnitude of the electric field across an axon membrane 1.2×10−8 m thick if the resting potential is -70 mV ?
