What does it mean to say that a signal is transduced? a. The signaling molecule enters the cell directly and elicits a cellular response. b. The signal is generated by the production of proteins. c. The physical form of the signal changes between the outside of the cell and the inside. d. The signal is amplified.

Hi everyone here's our next problem. It says signal transaction is the blank and blank of signal molecules in order to elicit an appropriate response. Well in signal transaction we recall that we have some sort of chemical signal binding to a receptor. Then we've got as a result various structural or chemical changes occur and that leads to enzyme activation. And then that goes on to catalyze the response. So we've got a signing two receptor and then some sort of changes occurring, causing enzyme activation. So when we look at our answer choices here we've got choice A says transmission and then conversion. Well this does describe what we have here. We have the signal molecules being transmitted being sent out and then buying two receptor and then some sort of change going on a conversion. So choice A transmission and conversion is the proper response here. Choice B is not correct. Choice B says elimination and reduction or we don't have an elimination of our signal molecules. Choice C says combination and integration. Signal molecules aren't combining with each other, they are binding to receptors they're being transmitted and choice D. Is alteration and interpretation. Um Well maybe you could argue an alteration but that's um kind of ignoring the fact of the signal molecule being sent and interpretation doesn't really mean anything in the context of this here. So choice the not a good answer to this. So again signal transaction is the choice a transmission and conversion of signal molecules in order to elicit an appropriate response.
