Suppоse thаt а chаnnel оbeys the cоncerted allosteric model (see below). The binding of ligand to the R state (the open form) is 20 times as tight as that to the T state (the closed form). In the absence of ligand, the ratio of closed to open channels is 105. If the channel is a tetramer, what is the fraction of open channels when 1, 2, 3, and 4 ligands are bound? The ratio of closed to open channels is 105 when no ligands are bound. The ratio of closed to open channels is [blank1] when one ligand is bound. The fraction of open channels is [blank2]. The ratio of closed to open channels is [blank3] when two ligands are bound. The fraction of open channels is [blank4]. The ratio of closed to open channels is [blank5] when three ligands are bound. The fraction of open channels is [blank6]. The ratio of closed to open channels is [blank7] when four ligands are bound. The fraction of open channels is [blank8].
