Question

Which of the following statements is true?

Answer 1

Answer:

The regulation of inflammatory responses at the site of infection is an example of paracrine signaling.

Explanation:

Paracrine signaling is a type of signaling where the cell communicates with their neighbor cells through the secretion of the signaling molecules. These signals move by the process of diffusion through the extracellular matrix.

Paracrine signaling helps in many biological activities in the body such as blood clotting, tissue repair, and reaction against allergens. Transfer of signals across a junction between two nerve cells is an example of practice signaling.

Answer 2

Answer: b.

Explanation:

Paracrine signalling is a type of cell-to-cell or cell signalling communication in which a cell produces a signal that causes changes in neighbouring cells, altering those cells' behaviour. One example of paracrine signalling is the transfer of signals between nerve cells through synapses.

Paracrine signalling functions are essential to amplifying and regulating an inflammatory response within a organ or tissue, and initiating a coordinated immune response involving different types of cells.

Hence, the correct option is b.
