Step-by-step explanation:
Given that,
Vo = ¼ Vmax
We are given the equation
Vo = (Vmax × [S]) / (Km + [S])
We want to find substrate [S]
Let substitute Vo = ¼Vmax into the given equation, so we have
Vo = (Vmax × [S]) / (Km + [S])
¼ Vmax = (Vmax × [S]) / (Km + [S])
Cross multiply
Vmax × (Km + [S]) = 4 × Vmax × [S] Divide both side by Vmax
(Km + [S]) = 4 × [S]
Km + [S] = 4•[S]
Make [S] subject of formula
4•[S] — [S] = Km
3•[S] = Km
Divide both sides by 3
[S] = Km / 3
[S] = ⅓ Km
So the substrate [S] is ⅓ Km when Vo is ¼Vmax
