Question

which of the followings are true about V0 and Vmax? A. The unit for each of them is M B. Vmax is a special V0 when all enzymes bind substrate C. Vmax is independent of enzyme concentration D. V0 can be determined using a linear correlation of product and time in the beginning of a reaction

Answer 1

Answer:

The correct answer is option B.

Explanation:

The unit of Vmax and Vo is moles per second. Km refers to the concentration of the substrate, which is needed to attain the maximum reaction velocity. In case, when [S] is far greater in comparison to Km then Vo will be close to Vmax.

Vmax relies upon the concentration of the enzyme, Vmax enhances with the concentration of the enzyme and becomes steady when all the active sites of enzymes get occupied. Vo increases with the enhancement in the concentration of the substrate with time. Thus, the correct answer is option B, that is, Vmax is a special Vo when all the enzymes combine with the substrate.
