Im studying membrane potential and need to answer how chemical and electrical forces act across the cell membrane. Is it that the ions (although both cations) are attracted to each other as well as ride down on their concentration gradient to the other side of the membrane? Im not sure if thats correct.
please help?What exactly is an electrochemical gradient?
I am no expert in membranes but I believe what you are talking about is combined forces due to electrical potential (from the presence of ions or an imposed voltage like in electroplating) and the chemical potential due to composition gradient. Living cells rely on a cell wall (a membrane) which maintains a composition gradient between the inside and the outside of the cell. hope this helps.
