What does it mean to say that a signal is transduced?
A) The signal enters the cell directly and binds to a receptor inside.
B) The physical form of the signal changes from one form to another.
C) The signal is amplified, such that even a single molecule evokes a large response.
D) The signal triggers a sequence of phosphorylation events inside the cell.

Question

Quizplus · Accepted Answer

Transduction refers to the process by which a signal is converted from one form to another. In the case of cellular signaling, the signal may be a chemical or physical stimulus that is transduced into a specific biochemical response inside the cell. This can involve a series of molecular interactions that result in the activation of downstream signaling pathways, ultimately leading to a physiological or behavioral response.
