Figure 5.

The effect of drag in the presence of elastic load K (= k). The dependences on drag (the horizontal axis) and the frequency (the vertical axis) are shown as color-coded contour plots. Darker colors indicate lower values. Drag is described by the ratio $\eta /{\eta }_0$, where η₀ = 1.0 × 10⁻⁶ kg/s. Frequency is represented by the ratio f/f₀, with f₀ = 4 kHz, which corresponds to the parameter values of the cell given in Table 1. (A) The amplitude (in mV) of the receptor potential. (B) The work (in zJ = 10⁻²¹ J) against the elastic load during a half cycle. (C) The work (in zJ) against the viscous drag during a half cycle. (D) Power output (in fW = 10⁻¹⁵ W) working against the viscous drag. To see this figure in color, go online.
