Null questions are questions in which one factor is not believed to have any association with what is mentioned in comparison to it. Examples of null questions include:

Do dogs care about the color of their chow?

This is a null question because animals generally don’t express a personal preference or dislike based on the color of their food.

Do children use more internet access than adults?

This is a null question because age doesn’t have a direct effect on the internet access of children or adults.

Andreyy89

Answer:

Vmax/ total enzyme concentration (Et)

Explanation:

According to the kinetics of Enzyme catalyzed reaction, the enzyme binds substrate and form the enzyme-substrate complex. The rate constant for this complex formation is K₁.

The enzyme complex later dissociates into the product and the enzyme itself ans the rate constant for this reaction is k₂. An enzyme-catalyzed reaction has the maximum velocity called Vmax.

The k₂ is also known as the turnover number which represents how many substrate molecules are converted into the products. The mathematical expression for this reaction is the:  

Vmax/ total enzyme concentration

Thus, Vmax/ total enzyme concentration (Et) is correct.
