- cofactor
- coenzyme
- substrates

Choose the correct answer from the options given below: - $K_m$ and $V_{max}$ of an enzyme preparation are 5 µM and 30 $µM min^{-1}$ respectively. Considering, $K_i$ value of competitive inhibitor is 60 µM, the velocity ($V_0$) of this enzyme-catalyzed reaction in the presence of 200 µM of substrate and 600 µM of competitive inhibitor is _______ $ µM min^{-1}$ (rounded off to two decimal places).

Enzymes - Biology
Enzymes are proteins that help accelerate metabolism or the chemical reactions in our bodies. They build some substances and decompose others. All living creatures have enzymes.
Our bodies naturally build enzymes. But enzymes are also in mass produce products and food.
One of the most important roles of enzymes is to succor digestion. The process of turning the food that we eat into energy is called digestion. For instance, there are enzymes in our saliva, pancreas, stomach, and intestines. They decompose fats, proteins, and carbohydrates. Enzymes make use of these nutrients for growth and cell repair.
