Question

The effectiveness of an enzyme is affected least by
A. Temperature
B. Concentration of the substrate
C. Original activation energy of the system
D. Concentration of the enzyme

Answer 1

Enzyme lowers the activation energy required to catalyse a reaction, and they are unaffected by the system's initial activation energy. The rate of reaction increases as the concentration of substrate or enzyme increases, people with O blood are more prone to stomach problems because of the high acidic contents in the stomach.

Complete answer:
Temperature, enzyme concentration, substrate concentration, pH, and other factors influence enzyme activity. The effectiveness of an enzyme, on the other hand, is unaffected by the system's initial activation energy. In other words, enzymes can only change the rate of a reaction, not the feasibility of the reaction. An infeasible reaction cannot be made possible by the enzyme. The original activation energy of the system determines the reaction's feasibility.

Hence, the Correct answer is option C. original activation energy of temperature,

Enzyme concentration, substrate concentration, pH, and other factors influence enzyme activity. The effectiveness of an enzyme, on the other hand, is unaffected by the system's initial activation energy. the system. Different enzyme inhibitors will also change reaction rate/substrate curves in different ways. The pH of water is a measurement of how acidic or basic it is. The range is 0 to 14, with 7 being the neutral value. Acidity is indicated by a pH less than 7, while a pH greater than 7 indicates a base. Acidic water contains more free hydrogen ions, whereas basic water contains more free hydroxyl ions.

Note:-
Substrate concentration: Increasing the substrate concentration speeds up the reaction to a point. Any increase in substrate will have no influence on the pace of reaction once all of the enzymes have bonded, as the available enzymes will be saturated and operating at their maximal rate.
