This\u00a0is an example of\u00a0phosphorylation, one of the two\u00a0methods of intracellular signaling. The other method\u2014second messengers\u2014can be seen in Ca2+<\/sup> signaling in muscle cells, which\u00a0leads to muscle contractions.\r\n\r\nThese are just two examples of the many, many body functions that rely on cell communication. As we discussed in opening this module, imagine again what would happen if we could not communicate in society. Now, with your new appreciation of cell communication, imagine what would happen if even a single aspect of that process broke down.\r\n

\r\n\r\nIt is tempting to view different topics as completely separate, but in fact the ideas we cover in this course are often connected to one another. If you don\u2019t retain the vocabulary from module to module, those connections can be missed. As you continue on, remember to come back and review the terms you\u2019ve learned in order to increase your depth of knowledge.\r\n\r\n
