Signal transduction pathways
A)are found strictly in multicellular organisms which require cell-to-cell communication.
B)are limited for use in sexual identification.
C)originally evolved in vertebrates.
D)are mechanisms of communication that probably evolved in ancient prokaryotes.

Question

Quizplus · Accepted Answer

Signal transduction pathways are mechanisms of communication between cells that allow cells to respond to signals or stimuli from their environment. This ability is essential for the survival of cells in both unicellular and multicellular organisms. While specific pathways may have evolved in more complex organisms, the concept of signal transduction likely originated in ancient prokaryotes.
