Cell Communication Practice

A neuron releases neurotransmitters into the synapse, which bind to receptors on a nearby muscle cell, causing it to contract.

A plant cell produces a hormone that travels through the vascular system to stimulate growth in a distant part of the plant.

. A yeast cell releases a signaling molecule into its surroundings, which binds to receptors on another yeast cell of a different mating type, initiating mating.
