Answer 1

In a particular chemical reaction, the reactants have more free energy than the products. what kind of reaction is this?

Answer: Exergonics

Exergonic means energy is exiting the system. In this, the reactants, or initial state, have more free energy than the products, or final state. Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy.
An exergonic reaction is a reaction that releases free energy. Because this type of reaction releases energy rather than consuming it, it can occur spontaneously, without being forced by outside factors.

After an enzyme catalyzes a chemical reaction, what happens to the enzyme?

Answer: The enzyme is not consumed by the reaction; it is still available to do the same reaction again.

During an enzyme catalyzed reaction the enzyme bonds with a specific substrate at the active site. This is called an enzyme-substrate complex. The substrate is converted into a specific product, but the enzyme remains unchanged. Enzymes accelerate reactions by factors of at least a million.
After the enzyme successfully catalyzes the chemical reaction, the products of the reaction are released and the enzyme is free to repeat the process.
