Phosphorylation is the process by which a ____ is added to a protein to activate it.

• acetyl

• sulfate

• phosphate

• nitrate

What is the advantage to amplification of a signal inside of a cell?

• moderates the signal so it is not to quick

• stops a signal from being transducted

• increases the cell response to a signal

• increases the reception of signal

The order of events involved with signal transduction in cells is

• stimulus - response - signal transduction

• reception - stimulus - response

• reception - signal transduction - response

• transduction - reception - stimulus

What is the purpose of transduction?

• send a signal to a target cell

• receive a signal from another cell

• respond to a signal pass along internally

• pass along a signal through the cell to the location where the cell response will occur.

Signal transduction is best defined as

• carrying a signal from outside a cell to the inside of that cell

• a detectable change in a cell's environment

• transmission of an electrical signal across a synapse

• gene expression in response to active transcription factors in the nucleus

Whether a ligand is polar or nonpolar affects its

• reception

• transduction

• response

Transduction step traditionally amplifies the signal, which of the following are NOT involved with transduction?

• secondary messengers

• protein modification

• phosphorylation cascade

• ligands
