Question

Quizplus · Accepted Answer

Paracrine signals are produced by one cell and bind to receptors on nearby cells, often regulating local cellular communication and behavior.

Answer: C 
 Autocrine signals are produced by a cell and bind to receptors on that same cell, often regulating its own function and behavior.

Option B and D are incorrect as parasitic signals and hormones are not signals that bind to receptors on nearby cells, but rather affect other organisms or distant parts of the body, respectively. Option E is not a commonly recognized term in this context.
