Effect of experimental manipulations in the I-V curve (bvis students, please illustrate a patch of membrane and the internal and external lonic solutions under the various conditions): Given below are the current-voltage (I-V) relations for an ion 'X', under normal, and a variety of experimental conditions. The normal curve is the solid line, '1.' For each of the following experimental conditions, indicate the I-V curve you believe would result from the manipulation. a) The number of number of channels (total conductance) in the membrane is doubled: b) A splice-variant is produced with half the original conductance: c) The [X], is reduced to 1/10 its original value, and [X]. remains the same: d) The concentration of [X], = [X].:Effect of experimental manipulations in the I-V curve (bvis students, please illustrate a patch of membrane and the internal and external lonic solutions under the various conditions): Given below are the current-voltage (I-V) relations for an ion 'X', under normal, and a variety of experimental conditions.
