1[s] = km for a simple enzymatic reaction. when substrate concentration is tripled, the rate becomes vmax.

The problem can be solved with the help of Michaelis Menten kinetics.

The equation can be written as

Where Vo = Initial velocity of the enzyme. This is also known as initial rate of the reaction.

Vmax = Maximum velocity

[S] = Substrate concentration

Km = Michaelis constant for the given enzyme.

When the substrate concentration is tripled, [S] becomes 3[S]

Let us plug this in Michaelis equation.

The new equation that we get is,

We have been given that Km = [S]

Let us write [S] in place of Km in our equation. We get,

On adding the values on the denominator we get,

We can cancel out [S] .

From the above equation, we can see that initial rate of the reaction (V₀) becomes 0.75 times Vmax

Therefore, when substrate concentration is tripled, the rate becomes 0.75 Vmax

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
