The Target Cell has Receptors on it, To which the Signalling Molecule binds to and This Alters the Shape or Activity of the Receptor which Triggers a Change inside the Cell. The Message from the Signalling Molecule is then Relayed again By a Chain of Chemical Messengers inside the Cell. Also, The Activation of G Protein leads to synthesis of Second Messengers, That Amplifies the Message to Other Cells Nearby. ]]> 2018-04-26 05:17:20 UTC https://padlet.com/lim_sj/signalling/wish/255511527 Cell Signalling vvimeshika https://padlet.com/lim_sj/signalling/wish/255511664 A signal arrives from a cell and is received by a receptor on the another cell on it’s cell surface membrane. This involves transport of hormones and glycoproteins. The signal will be received only if the receptor is complementary to the signal. After the signal is received a response or triggers of a chemical reactions. This activates G protein and so more enzymes will be activated to carry a chemical process.]]> 2018-04-26 05:18:03 UTC https://padlet.com/lim_sj/signalling/wish/255511664 Signal binds to receptor, activating the protein which then activates the G protein. This will activate the 2nd messenger which leads to a signalling cascade. tanszejean07 https://padlet.com/lim_sj/signalling/wish/255511744 2018-04-26 05:18:47 UTC https://padlet.com/lim_sj/signalling/wish/255511744 zhichengq7 https://padlet.com/lim_sj/signalling/wish/255511799 G protein]]> 2018-04-26 05:19:16 UTC https://padlet.com/lim_sj/signalling/wish/255511799 Signal amplifying inside cell azhengjiet https://padlet.com/lim_sj/signalling/wish/255511851 2018-04-26 05:19:38 UTC https://padlet.com/lim_sj/signalling/wish/255511851 Wow kamenrider1500 https://padlet.com/lim_sj/signalling/wish/255511884 Such signal

Hydrophillic hormones bind to specific receptor proteins on target cell.
2. The receptor protein changes shape and activates the G protein.
3. The G protein activates an enzyme to many produce second messengers.
4. The second messenger molecules activate enzymes which then activate further enzymes. This leads to the amplification of the original signal.
5. A final enzyme produced brings about the required change in cell metabolism.]]> 2018-04-26 05:21:13 UTC https://padlet.com/lim_sj/signalling/wish/255512101 G-Protein lesparkk https://padlet.com/lim_sj/signalling/wish/255512107 G-protein activates a specific enzyme to synthesise the second messengers and relays the message by diffusing through the cell. ]]> 2018-04-26 05:21:15 UTC https://padlet.com/lim_sj/signalling/wish/255512107 A typical cell signalling pathway: suleman14b https://padlet.com/lim_sj/signalling/wish/255512135 1. Stimulus or signal recieved by specific cell surface receptor. (Receptor-ligand binding)
2. Signal is converted to a message by secondary messengers (transduction)
3. Message transmitted to appropriate effector by G-Protein.
4. Effector makes appropriate response.]]> 2018-04-26 05:21:21 UTC https://padlet.com/lim_sj/signalling/wish/255512135 A signal arrives at the target cell and binds to the specific receptors on the surface membrane. It changes the shape of the receptor and activates G-Protein. Activated G-protein will later activate an enzyme to produce many second messengers and activates many enzymes. Activated of enzymes cause signal to be amplified. A final enzyme is produced to carry out the response. bryanctc911 https://padlet.com/lim_sj/signalling/wish/255512138 2018-04-26 05:21:23 UTC https://padlet.com/lim_sj/signalling/wish/255512138 Cell signalling tanszejean07 https://padlet.com/lim_sj/signalling/wish/255512228 Signal binds to a receptor on a protein molecule, activating the G protein. The second messenger will be activated and a signalling cascade occurs.
