Question

Which component of the signal transduction pathway in rod cells is found in the cytosol of the cell?

Answer 1

The right answer is cGMP.

cGMP exists in two forms: soluble in the cytosol, and insoluble, bound to the plasma membrane. The subcellular distribution of these two forms varies according to the tissue: in the adult liver and platelets, the enzyme is especially soluble; it is especially particulate in the fetal liver or in regeneration in the intestinal mucosa.

Answer 2

The correct answer is cGMP retinal rhodopsin traduction.
Signal transduction is the cellular which comments on signal to another. An ordered sequence of the biochemical reaction is needed for signal transduction processes to take place which leads to cellular response. Some of the signal transduction are 
(i) Desensitization of signals
(ii)  Amplification of constant signals
(iii)  A specification of cues
(iv)  Integration of multiple signals.

Some of the components of signal transduction pathway are 
Signal, machinery that translates and amplifies to cell response, and receptor for the message.
