There are two major participants in every cell communication activity. The one that is giving communication, and the one that receives communication. Some also communicate through direct and indirect contact, which is also called local and long-distance signaling. Which of the following is an example of long-distance signaling occurring in the body?

A. paracrine signaling
B. systematic signaling
C. synaptic signaling
D. hormonal signaling

Endocrine signals are transmitted more slowly than paracrine signals because

A. the ligands are transported through the bloodstream and travel greater distances.
B. the target and signaling cells are close together.
C. the ligands are degraded rapidly.
D. the ligands don't bind to carrier proteins during transport.

What is the advantage of a signal transduction cascade?

A. The receptor/ligand becomes the transcription factor and affects gene expression directly.
B. Activation of molecules by phosphorylation allow for amplification of the signal as well as multiple responses to the signal.
C. It allows the signal to be active for a very long time.
D. It utilizes only tyrosine kinase receptors.
