Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.0 x 10 7 N/C. What is the magnitude of the force on a calcium ion with charge +e? What is its acceleration?
Is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location?
What would change the acceleration: mass of the particle? diameter of the particle?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. Assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.1x10^-6 C/m^2. What is the magnitude of the electric field within the cell membrane? Then find the magnitude of the electric force that would be exerted on a potassium ion (K+; charge=+e) placed...

A cell membrane consists of an inner and outer wall separated by a distance of approximately 10nm. Assume that the walls act like a parallel plate capacitor, each with a charge density of 10-5C/m2, and the outer wall is positively charged. Although unrealistic, assume that the space between cell walls is filled with air. part A: What is the magnitude of the electric field between the membranes? Part B: What is the magnitude of the force on a Mg++ ion...
Calcium ions (CA2+) are stored in the smooth ER. Some signaling pathways in the cell cause the ER to release the calcium ions into the cytoplasm, which causes the calcium ion concentration in the cytoplasm to increase and at the same time the calcium ions concentration in the ER to decrease. Once the signaling pathways is turned off, the calcium is returned to the ER so that the concentration of calcium in the ER is very high and the concentration...
