Question:
The effectiveness of an enzyme is affected least by
The effectiveness of an enzyme is affected least by
Updated On: Jun 18, 2022
- temperature
- concentration of the substrate
- original activation energy of the system
- concentration of the enzyme
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The enzymes lower the requirement of activation energy for catalyzing a reaction and these are least affected by the original activation energy of the system. Enzymes are thermolabile. Increase in substrate concentration or enzyme concentration increases the rate of reaction.

Enzymes
Catalysts of biological systems can be known as Enzymes. Enzymes helps us to perform the huge variety of biochemical reactions that encompass in life are all mediated by a series of activities.
Properties of Enzymes:
Following are the properties of enzymes:
- Enzymes initiate and speed up the reaction
- The enzyme’s activity is ph dependent
- Enzymes have the capacity to forward and reverse the reaction but do not decide the direction of the biochemical pathway
- An enzyme has a particular area on which the substrate interacts to produce the desired product
- Enzyme becomes unstable at varying ph, high temperature and heat
- It have protein like characteristics
- Substrates can be catalyzed with a small number of enzymes
- Enzyme activity represents absolute, relative, group and stereo specificities
- Some enzymes perform regulatory function
- It minimise activation energy (Ea)
- The enzymes remain unaffected before and after the product formation and it can be reused
- They are soluble both in water and NaCl.
