An enzyme that follows simple michaelis–menten kinetics has an initial reaction velocity of 10 μmol⋅min−1 when the substrate con
svet-max [94.6K]

The Vmax of the enzyme is 12 μmol⋅min−1

We use Michaelis-menten equation,  which is given by;

V=\frac{Vmax(S)}{Km+(S)} \\

Where v is velocity of reaction

Vmax = maximum rate achieved by the system

[S] = concentration of a substrate

K_{m}= Michaelis constant

Given V_{0} = 10umolmin^{-1}

[S] = 5km

Now, we calculate Vmax:

10umolmin^{-1} = \frac{Vmax*(5Km)}{Km+5Km}

Km = 1

10=\frac{5KmVmax}{6Km}

\frac{10*6}{5} =Vmax

Vmax =12 μmol⋅min−1

Answer:

The Answer is: A. The North Star

Explanation:

Pluto is part of the Solar System as is the Asteroid Belt and Jupiter's moon. The North Star, Polaris is about 430 Light Years away. That is, it is far enough away that light has to travel 430 years in order to reach between here and there.
