Option A is correct
Adding an enzyme to decrease the activation energy of the reaction
Enzymes are the biological catalyst. They are proteins in nature. They are naturally found in humans,animals,micro-organisms,plants etc. They catalyze the chemical reactions by lowering activation energy and without being consumed in it.
Answer: Option (a) is the correct answer.
Explanation:
An enzyme is defined as a substance which acts as a catalyst and it is produced by a living organism to bring about a specific biochemical reaction.
An enzyme actually helps in increasing the rate of a reaction by combining at a specific site and like a catalyst an enzyme does not get consumed in a chemical reaction.
An enzyme binds with the substrate and results in the formation of a stable enzyme-substrate complex.
Like a catalyst, an enzyme also helps in lowering the activation energy.
thus, we can conclude that adding an enzyme to decrease the activation energy of the reaction would make a chemical reaction most likely proceed at the fastest rate.
