How can chemicals activate a pathway
WebSpecific signals can trigger a sudden increase in the cytoplasmic Ca 2+ levels to 500–1,000 nM by opening channels in the ER or the plasma membrane.The most common signaling pathway that increases cytoplasmic calcium concentration is the phospholipase C (PLC) pathway.. Many cell surface receptors, including G protein-coupled receptors and … WebPathways activated by cell surface receptors include synthesis of second messengers (non-protein signaling molecules) such as calcium or cyclic AMP which propagate …
