Question

Question 3 (1 point) Signaling between cells can occur over long or short distances. Which of the following statements about this topic are correct? In contact-dependent signaling, there is no signal molecule released. In autocrine signaling, the signaling cell and responding cell are the same: the cell is signaling itself. The impact of growth factor on the cells of a developing embryo is an exaîmple of autocrine signaling. nThe impact of adrenaline on various tissues of the body during fight-or-flight response i an example paracrine signaling. The impact of neurotransmitter signals between nerve cells is an example of paracrine signaling. Save

Explanation / Answer

autocrine signalling thebsignalling molecule cell and responding cell are same the cell is signalling itself.

The impact of adrenaline on various tissue of body during fight and flight response ia an example of paracrine signalling

The imapct of neurotransmitter against between nerve cell is an example of paracrine signalling .

Note- the autocrine signal itself by release of signal molecule for itself while paracrine release sognal for surrounding tissue and is cell to cell communication where cell produces signal to induce changes in neighbour cells.
