The michaelis-menten equation is an expression of the relationship between the initial velocity, v0, of an enzymatic reaction and substrate concentration, [s]. there are three conditions that are useful for simplifying the michaelis-menten equation to an expression from which the effect of [s] on the rate can be more readily determined. match the condition (e. g. [s] = km) with the statement(s) that describe it:

1. doubling [s] will almost double the rate.
2. half of the active sites are occupied by substrate.
3. about 90% of the active sites are occupied by substrate.
4. doubling [s] will have little effect on the rate.
5. less than 10% of the active sites are occupied by substrate.
6. this condition will result in the highest rate.

Option 2, Half of the active sites are occupied by substrate

Explanation:

Michaelis-Menten expression for enzyme catalysed equation is as follows:

Here, is Michaelis-Menten constant and [S] is substrate concentration.

When [S]=Km

Rearrange the above equation as follows:

when [S]=Km, the rate of enzyme catalysed reaction becomes half of the maximum rate, that means half of the active sites are occupied by substrate.

Therefore, the correct option is option 2.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
