How are signals received and interpreted? (cell signaling)

Answer 1

Cell signaling is usually done via chemical signalling such as hormones. Hormones are released by one cell and received by another. The signal gives the receiving cell a set of instructions. There are different methods by which those cells receive it. In some cases, the signal never inters the cell, rather it attaches to a receptor (some protein structure on the cell's surface) and that receptor allows for a chemical chain reaction to occur within the cell. This is called a chemical cascade. If you liked my answer or would like to know in further depth, consider scheduling a lesson with me! I hope this helped!
