8. Signal transduction is the process whereby one type of signal is converted to another.

Group of answer choices

True

False

Answer 1

Ans. True

• The transformation of the information in the signal from one form to another is called signal transduction.
• In signal transduction, extracellular signals are converted into intracellular signals: A signaling molecule (ligand) reaches to  target cell and binds to a specific receptor. This activates a signaling cascade involving enzymes and molecules (second messengers), which again leads to a specific reaction. Via signal amplification, the number of signaling molecules is increased at every step of the signal cascade.
