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 the meaning of these terms: E, S, ES
Respectively for Enzyme's effectiveness, Substrate, and complex of enzyme-substrate
Respectively for Enzyme, Substrate, and Enzyme-Substrate complex
What is the meaning of these terms: [E], [S], [ES]
Respectively for concentration of enzyme, concentration of substrate, and concentration of enzyme-substrate complex
Respectively for amount of enzyme, concentration of substrate, and concentration of enzyme-substrate complex
Velocity, V=dtd[P] is the equation for enzyme's velocity. Which of the following information are correct?
Velocity is the rate of product formation over time
Velocity is a measurement of rate
Velocity measures the depletion (kekurangan) of the substrate
Velocity measures the formation of the product
Select the correct statement(s) related to Michaelis-Menten plot (graph)
At zero concentration of substrate, meaning [S]=0, the velocity is zero
As the concentration of the substrate increases, the formation of product also increases
The plot is generating using different concentration of substrate
The plot is generating using different concentration of enzyme
What is Vmax?
With a fix concentration of enzyme, the formation of product will not increase even if you add more substrate
A maximum value for Velocity
Related to a situation where the Michaelis-Menten plot reaches a plateau ('flat')
Maximum substrate that is been converted to product
What is Km?
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 kilometer, how far the enzyme can move
Km is Michaelis-Menten constant
Affinity is a word to describe how effective is the binding between the enzyme and the substrate. What is the relationship of Km with affinity?
High Km, High affinity
High Km, Low affinity
With lower Km, the enzyme can reach Vmax faster
