Document Summary

Cell signaling: cell signaling helps ensure that crucial cellular activities occur in the right cells and the right time. The three main types of plasma membrane receptors are g protein coupled receptors, receptor tyrosine kinases, and ion channel receptors. This also causes a gtp to displace the. Gdp, activating the g protein: the activated g protein eventually binds to an enzyme, altering its shape and activity. The enzyme then triggers a new step, leading to a cellular response. Receptor tyrosine kinase: kinase any enzyme that catalyzes the transfer of phosphate groups, receptor tyrosine kinase (rtk) a major class of plasma membrane receptors characterized by having enzymatic activity. This dimerization process activates the tyrosine kinase regions on the monomers, causing them to add phosphates from atp to each tail: this activates the receptor, causing it to be recognized by other relay molecules in the cell. These proteins bind to the tyrosine and activate different transduction pathways.
