Any voltage is a difference in electric potential between two points-for example, the separation of positive and negative electric charges on opposite sides of a resistive barrier.
An electric potential (also called the electric field potential or the electrostatic potential) is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the work done by an electric field in carrying a unit of positive charge from infinity to that point.
resting potential of animal cells is determined by predominant high permeability to potassium and adjusted to the required value by modulating sodium and chloride permeabilities and gradients.

: The cell releases second messenger molecules in response to exposure to extracellular signaling molecules—the first messengers.
Because peptide hormones and neurotransmitters typically are biochemically hydrophilic molecules, these first messengers may not physically cross the phospholipid bilayer cell membrane to initiate changes within the cell directly—unlike steroid hormones, which usually do. This functional limitation necessitates the cell to devise signal transduction mechanisms to transduce first messenger into second messengers, so that the extracellular signal may be propagated intracellularly.
An important feature of the second messenger signaling system is that second messengers may be coupled downstream to multi-cyclic kinase cascades to greatly amplify the strength of the original first messenger signal
所以通常使用second messanger 的系統有兩個原因 1. the first messengers 無法直接穿過細胞膜的時候 2. 刺激很微小 需要放大訊號的時候
但是也有缺點 1. 有些scond messanger 需要酵素反應來合成 或活化 Secondary messenger systems can be synthesized and activated by enzymes 離子本身可以進入細胞 則速度更快 2. 多步驟的放大反應 也相較離子直接進入細胞 要花更多時間
