Functions of Signal Transduction (select any/all that apply):
1. a second messenger
2. Cell-cell communication
3. Cell’s response to environment
4. Intracellular homeostatsis- internal communication
The answer of the provided question is-
The functions of signal transduction are to activate a second messenger.Signal transduction also helps in cell-cell communication and it also helps a cell to respond to its environment. Signal transduction helps in maintaining the intracellular homeostasis and internal communication within a cell. So, the correct answers of the question are option "1" i.e. " a second messenger",option "2" i.e. " cell-cell communication", option "3" i.e. " cell's response to environment", option "4" i.e. " intracellular homeostasis- internal communication".
Signal transduction is a process through which signals or information (from the outside environment or from another cell of the body) transfer or transmit to a target cell. At first, the signal or the primary messenger (from the outside environment or from another cell of the body) binds to its particular receptor present on the cell membrane of the target cell. Now the receptor transfers this signal inside the cell with the help of various methods such as the receptor can activate some molecules ( the second messengers) . Now, the second messenger carries the signal to specefic target part or organelle inside the cell and ultimately thus the signal causes change (such as activity of a gene can be altered) inside the cell. Thus,with the help of signal transduction cells communicate with the other cells of the body. Various changes in the immediate environment of a cell as well as cell's response to that change are performed with the help of signal transduction. Intracellular homeostasis ( the ability to maintain a optimum condition necessary for the survival of the cell ) and internal communication within a cell can also be maintained with the help of signal transduction.So, all the options mentioned in the question are correct.
