Question

A force that drives an ion through a membrane channel depends on the: charge on the membrane. difference in electrical potential across the membrane. size of the channel. size of the ion. size of the membrane. A hydropathy plot is used to: determine the water -solubility of protein. deduce the quaternary structure of a membrane protein. determine the water content of native protein. extrapolate for the true molecular weight of a membrane protein. predict whether a given protein sequence contains membrane-spanning segment

Explanation / Answer

Question 2:The correct answer is:the difference in electrical potential across the membrane.

Reason:There exists membrane potential difference on either side of the membrane and this drives an ion through the membrane.

Question 3:The correct answer is: predict whether a given protein sequence contains membrane-spanning segments.

Reason:The above answer best can be depicted via hydropathy plot.
