Question

The amount of energy needed for a reaction to take place is the activation energy. Enzymes can lower the activation energy of a chemical reaction. Which of the following describes a way that this could happen?

Question 9 options:

The enzyme distributes ATP to cells and then is destroyed.

More substrate is added by the enzyme.

Molecules can be brought together so they will bond more easily.

The enzyme separates molecules from each other.

Answer 1

THe third option would be a good choice.

Answer 2

The enzyme separates molecules from each other.

Step-by-step explanation:

Activation energy is an amount of energy that "pushes" the enzyme reaction to take place. The higher the value of this energy, the slower the enzymatic reaction will take place, so some enzymes can cause the activation energy to decrease, in order to accelerate the enzymatic process.

Generally, enzymes decrease the activation energy by modifying the physical structure of the molecule, separating some parts, or leaving the bonds weakened so that it is possible to break that molecule more easily. Enzymes can also participate in the reaction to reduce the activation energy.
