Chapter 9.2, Problem 1SB
Summary Introduction
To review:
The role of protein kinase and its role in the signal transduction pathway.
Introduction:
The transmission of the physical or chemical signals by a cascade of events in the cell is termed as signal transduction. This signal results in the production of the response by the cell. The ligands that elicit the response bind to the receptors that induce a cascade of phosphorylation to induce cell response.
