Signal transduction

... may be of one type or several, as in the case of insulin , which triggers diverse and systemic effects. Hormones signalling is elaborate and hard to dissect. A cell can have several different receptors that recognize the same hormone, but activate different signal transduction pathways; or different horm...

It is important to appreciate that it is the receptor that dictates the neurotransmitter's effect. Mechanism of action Within the cells , small-molecule n...

Both of these processes must only occur when glucose is abundant, or problems occur. Distinguishing isozymes Isozymes (and allozymes) are var...
