Large number of receptors reduces cellular response time - Q-bio
... Short Abstract — Cells often have tens of thousands of receptors, even though only a few activated receptors can trigger full cellular responses. The reason for the overabundance of receptors is unknown. We suggest that the large number of receptors results in a reduced variability of the time to ac ...
