What is the role of Michaelis-Menten equation?
To calculate the free energy
Mathematically explain the relationship of enzyme's velocity and the substrate concentration
Mathematically explain the saturation of enzyme in substrate
What is Vmax ?
(you can choice more than one answer)
With a fix concentration of enzyme, the formation of product will not increase even if you add more substrate
Related to a situation where the Michaelis-Menten plot reaches a plateau ('flat')
A maximum value for Velocity
Maximum substrate that is been converted to product
Apa itu nilai Km?
(Pilihlah lebih dari satu jawaban)
The unit for length is cm. The unit for Km is substrate concentration
Km is the value of [S] when the velocity is half Vmax
Km is Michaelis-Menten constant
Km is kilometer, how far the enzyme can move
