CELL COMMUNICATION
| Question | Answer |
|---|---|
| what are the classes of cell communications? | Direct contact local signaling long distance signaling |
| what is signaling tranductions pathway? | series of steps that converts signaling into response. |
| what is paracine and synaptic signaling? | types of local signaling. paracine signaling is when cell secrets hormones to several receiving cell. synaptic signaling usual occurs in neurons. |
| what are the processes of cell signaling? | 1) ligands 2) reception 3) transduction 4) response |
| what happens during reception during the cell signaling process? | The first messenger finds and targets a cell. |
| What happens during transduction? | the signal is converted into a form for the cell to respond to. |
| what happens during response during cell signaling process? | the cell responds to the signal with an action. |
| where are the intracellular receptors? | located in the cytoplasm or the nucleus membrane |
| where are the cell membrane receptors? | integral membrane of the cell membrane |
| what are the three types of membrane receptors? | G-protein, Receptor tyrosine kinase, ion channel receptors |
| what are the advantages of having many steps in signaling? | signals can be regulated. amplification of original signal |
