When a signaling molecule binds to a receptor located in the cell membrane, the signal / information is carried further into the cell via the receptor. The signal / information will lead to some type of change inside in cells in response to the signal it received. What this change is depends on the type of signaling molecule that binds to the cell (but may also depend on the type of cell that the signaling molecule binds to). In some cases, the change that takes place in the cell will be rapid and take a few seconds off that the signaling molecule binds to the receptor until the change takes place (fast signaling pathway). In some cases the change will take much longer, perhaps several hours from the time the signaling molecule binds to the receptor until the change occurs in the cell (slow signaling pathway). Explain how the signal path would be be able to look when it is fast and what it could look like when it is slow.
