The reactions that occur in cells are both anabolic (building up) and catabolic (breaking down). The catabolic reactions provide the energy for the anabolic reactions. The sum total of all catabolic and anabolic reactions in the cell is called metabolism.
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
Substances that are added to a reaction to speed it up are called catalysts. Catalysts work by providing an alternative pathway with lower activation energy for the reaction to occur, thus increasing the rate of the reaction without being consumed themselves.
A reversible reaction is one where the products can reform the original reactants. Forward and reverse reactions occur simultaneously until equilibrium is reached. This can be represented by a double arrow in a chemical equation.
METABOLISM
Intermediates are compounds formed within a metabolic pathway(which is a group of biochemical reactions that occur in a sequence- Anabolic or catabolic)
A double arrow in a chemical reaction indicates that the reaction is reversible, meaning it can proceed in both the forward and reverse directions. The reaction can reach an equilibrium where the forward and reverse reactions occur at the same rate.

A catalyst is a substance that aids in the chemical reaction process by increasing the rate of the reaction without being consumed itself. Catalysts work by providing an alternative pathway with lower activation energy for the reaction to occur.
Breaking down of macromolecules into small particles is called a catabolic process. In any catabolic process there is a release of energy. Anabolic reaction combines small particles into a macro molecule and energy is conserved in such a process.
A catalyst can increase the rate of a reaction by lowering the activation energy needed for the reaction to occur. Catalysts provide an alternative reaction pathway with a lower activation energy, allowing the reaction to happen more quickly.
When the reaction reaches a point where reactants produced is equal to products produced the reaction is said to be in equilibrium. If that is what you afre talking about
The reverse reaction of hydrochloric acid and magnesium would be magnesium chloride and hydrogen gas. This can occur through the displacement reaction between the magnesium and hydrogen in the presence of an acidic solution like hydrochloric acid.
