Alright class! So today, we will be discussing cells so pay close attention! Cells have an agent that influences the properties of cells that is called a signal.
Who said cells couldn't have fun and had to be doing scientific things all the time? Right boys?!
Right boss! I mean, working all the time is stressful for us too. We also need times to communicate with one another and let loose!!
Cell communication, also referred to as cell signaling involves both incoming and outgoing signals. Cell signaling is important because cells need to respond to a changing environment.
Wow, that was exhausting! We always change as our environment is changing, and now is time for some rest.
For example, Direct intercellular signaling occurs when a signaling molecule passes between the cytosol of adjacent cells through a cell junction. During cellular signaling, the signaling molecule binding to it causes the receptor to become activated.
