Question

What kind of signaling is occurring in a cell where a receptor protein binds a signaling molecule produced by the same cell?

1) Autocrine signaling
2) Paracrine signaling
3) Endocrine signaling
4) Synaptic signaling

Answer 1

The type of signaling occurring in this cell is autocrine signaling.1) Autocrine signaling

Step-by-step explanation:

In a cell where a receptor protein binds a signaling molecule produced by the same cell, the type of signaling that is occurring is autocrine signaling. Autocrine signaling occurs when a cell responds to its own signaling molecule, meaning that the signaling cell and the target cell are the same or similar. This type of signaling is important in embryological development, pain sensation, inflammatory responses, and programmed cell death.
