What is a signal transduction pathway?

Answer 1

Signal transduction refers to the transmission of a molecular signal , in the form of a chemical modification.

This entails the passage of protein complexes along a signaling pathway, which in turn sets off a cellular biochemical reaction.

A specific receptor on the cell surface or inside the cell is activated by an extracellular signaling molecule, which sets off a series of biochemical reactions inside the cell known as the signaling cascade that ultimately result in a response.

One signaling molecule can cause a response involving hundreds or millions of molecules, depending on the cell, and the response can change the cell's metabolism, shape, gene expression, or ability to divide.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
