Bio-signaling: Signal Transduction

The equilibrium concentration of ligand binding sites on the protein

The process by which cells translate extracellular signals into specific responses (correct)

The ability for cells to produce, receive, and respond to internal signals

The process of membrane permeation by ions and polar molecules

The concentration of ligand at which half the ligand binding sites on the protein are occupied (correct)

The rate of permeation of adrenaline through the cell membrane

The equilibrium concentration of water molecules in the cell membrane

The dissociation of bio-signaling molecules from the plasma membrane

To prevent the entry of first messengers from the external environment

Due to their high permeability to water

As a result of high rates of adrenaline permeation

Because of the low permeability of small molecules such as urea (correct)
