As you said, the movement of ions are often intermediated by ion channels,
which are basically proteins. Those ion channels can be modulated in a couple
of ways. Some of them are modulated by certain molecules, eg. Ca2+, Mg2+
transmitters. Some of them are modulated by voltage. Their probability of
being open can change dramatically when voltage across the membrane changes.
The ions move passively according to the chemical potential.

for phD students, it is not critical yet. but for postdocs looking for faculty
positions, big PI is more important than Cell/Nature/Science paper.
remember the mm faculty in MIT from Roger Tsjen's lab? she was discussed on
this board a while ago. her publication was so so, not even close to the
publications by the 2 previous grad students from our lab. but still, she is a
faculty and my ShiXiong are still postdocs.
let's put it this way. |
