Question

The unequal distribution of charge in solutions on either side of a membrane will lead to a ________ of charge across the membrane and a ________ of counter ions in a region close to the membrane.
a. collection : clustering
b. collection : restriction
c. buildup : restriction
d. separation : restriction
e. separation : clustering

Answer 1

Answer:

e. separation : clustering

Explanation:

When the two sides of the membrane have an unequal buildup of charged particles, there is a charge separation on either side of the membrane. One side of the membrane becomes positively charged while the other becomes negatively charged. This also occurs during resting potential when the cytosol present close of the membrane of the neurons become negatively charged with respect to the extracellular fluid present on the other side of the membrane. This allows the accumulation of oppositely charged particles (here, the positively charged particles in the inside) across the membrane.
