What an analogy for Channel Proteins and Receptor Proteins?
- 6 years agoFavorite Answer
A channel protein is like a road with some restrictions on it, only molecules of certain size and charge can use it to get into the cell. A receptor protein is like a key lock, very specific and only the right key can use it. Once the proper molecule or key comes into contact with it, a few things can happen depending on the specific receptor.
