49.
The cells that make up multicellular organisms send, receive, and respond to a variety of signals. Synaptic signaling is a form of cell-to-cell communication in which…
a cell produces a signal released into the bloodstream to be carried to specific distant organ.
adjacent cells pass molecules from one cell\'s cytoplasm to another through cell junctions.
the same cell that produces a signal also responds to the signal.
a neuron produces a chemical that induces changes in local, nearby, neurons.

50.
Match each description to the appropriate signal transduction stage.
reception transduction response
A. phytochrome receptor is activated by light signal. B, Specific genes are expressed. C. Proteins are activated through phosphorylation cascade. D. Second messenger activates specific protein kinase.
Expert's answer
