Key Equations

$$J = -D \frac{dC}{dx}$$
$$v = \frac{V_{\max}[\text{S}]}{K_m + [\text{S}]}$$
$$E_{\text{ion}} = \frac{RT}{zF}\ln\frac{[\text{ion}]_{\text{out}}}{[\text{ion}]_{\text{in}}} = \frac{61.5 \text{ mV}}{z}\log\frac{[\text{ion}]_{\text{out}}}{[\text{ion}]_{\text{in}}} \quad \text{(at 37°C)}$$
$$E_{Na} = \frac{61.5 \text{ mV}}{+1}\log\frac{145}{12} = 61.5 \times 1.082 \approx +67 \text{ mV}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
