It allows release of H+ ions

it allows food to enter taste pores and contact taste cells

we can only taste substances in liquid form

food must be broken down to ions in order to pass through membrane channels

saliva must enter taste receptors to mediate taste sensation

Are modified nerve cells that collect information from the receptor cells 

Are presumptive stem cells that replace the receptor cells at regular intervals

Are glial cells that maintain a constant chemical environment for the receptor cells 

Are glial cells that produce mucus or saliva to wash fluids into the vicinity of the receptor cells 

Are glial cells that provide structural support for the receptor cells
