Cell signaling allows cells to communicate with each other through signal transd

Question

Cell signaling allows cells to communicate with each other through signal transduction pathways. When a nerve impulse reaches the end of one neuron, the impulse triggers the release of neurotransmitters used as signal molecules into the space between adjacent neurons. How do adjacent cells respond to these signal molecules? Put the three phases in the signal transduction pathway in order. Neurotransmitters are released into the space between adjacent nerve cells. Signal transduction pathway ends Protein receptors on neurons bind to neurotransmitters. If enough neurotransmitters are present, an electrical current moves along the receiving neuron in response Neurotransmitters cause changes in protein receptors that allow ions to cross the cell membrane

Explanation / Answer

Answer:

1. Neurotransmitters are released into the space between adjacent nerve cells.

2. Protein receptors on neurons bind to neurotransmitters.

3. Neurotransmitters cause changes in protein receptors that allow ions to cross the cell membrane.

4. If enough neurotransmitters are present, an electrical current moves along the receiving neuron in response.

5. Signal transduction pathway ends.
