please help, I think the answer is on chegg if you have that
This graph illustrates how an enzyme catalyzes reactions in biological systems. To start a reaction, a certain amount of energy must be absorbed by the reactants. This is called the energy of activation. Which of the following is the normal energy of activation?

Answer 1

Answer: a is energy of activation.

Explanation: Because energy of activation is the minimum energy which must be provided to a chemical or nuclear system with potential reactants to result in a chemical reaction, nuclear reaction, or various other physical phenomena.

Answer 2

The chemical substance which helps to convert the reactant to the products easily and fastly is called an enzyme. These are a few examples of an enzyme:-

• Pepsin
• Trypsin
• Bile juice

Every reaction must reach the threshold to complete the reaction. The minimum energy required to reach the threshold is called activation energy.

The enzyme decreases the threshold energy so that reactant easily converts into a product.

Hence, the a denotes the normal activation energy.
