Question 3

Which of the following equation represent the reciprocal of Michaelis-Menten equation

Accepted Answer

$$\frac{1}{v} = \frac{{{K_m} + \left[ S \right]}}{{{V_{\max }}\left[ S \right]}}$$

Answer

$$\frac{v}{{\left[ S \right]}} = - \frac{v}{{{K_m}}} + \frac{{{V_{\max }}}}{{{K_m}}}$$

Answer

$$v = \frac{{{K_{cat}}}}{{{K_m}}}{\left[ E \right]_t}\left[ S \right]$$

Answer

$$v = \frac{{{K_{\max }}\left[ S \right]}}{{{K_m} + \left[ S \right]}}$$
