1. Acetylcholine does not penetrate lipid cell membranes because it is highly polar, but it can can bind to and activate ion-channels in the membranes of muscle cells. These channels allow through calcium ions.

2. When serotonin binds to a channel, it allows positively charged ions to flow through, such as sodium, potassium, or calcium.
