Summary Introduction
Introduction:
The voltage-gated and ligand-gated channels are the communication channels that allow the signal transductions among various types of cells. The voltage-gated and ligand-gated channels both open under the appropriate stimuli and lead to the initiation of cellular changes that generate a pathway to bring about the required response.

What is the main benefit of cell signaling via direct physical contact and cell signaling over short distances (ex: nerve cell signaling)?
In this mechanim of receptor regulation, there is uncoupling of the signaling pathway. Even though the ligand is bound to the receptor located in the plasma membrane, downstream signaling is not occuring. This is best described as: Answers A-D A receptor internalization B receptor desensitization C receptor sensitization 5 D receptor downregulation
Which is true about signaling receptors?
They are transmembrane proteins that have binding sites for extracellular activated proteinsto effect changes inside the cell.
They are transmembrane proteins that have binding sites for extracellular DNA-binding proteins to effect changes inside the cell.
They are transmembrane proteins that have binding sites for extracellular enzyme effectors to effect changes inside the cell.
They are transmembrane proteins that have binding sites for extracellular messengers to effect changes inside the cell.
