To put it simply, enzymes are proteins that catalyze or speed up the reaction of processes within cells. So when an enzyme attaches to a process, such as metabolism, it can speed up the process. Enzymes regulate those processes by either being "on" or "off", meaning that some energy source such as ATP transfers a phosphate to the enzyme, changing its shape and turning it "on", and allowing it to catalyze the reaction. A good example of this is oxidative phosphorylation, in which the transfer of electrons and protons across the cell membrane at the electron transfer chain site move into a mitochondria, increasing the concentration of protons inside it, and the protons move from this concentrated proton area to the less concentrated area outside the mitochondria through an enzyme called ATP synthetase. This transfer across the membrane creates energy inside the ATP synthetase, like a water-mill, and the synthetase changes ATP into ADP and phosphorylated water, and ADP back into ATP. This facilitates an energy cycle, and thus affects metabolism.
Enzymes lower the free activation energy, which is the free energy it takes to start a reaction.
Enzymes - like any other catalyst - lower the energy barrier for a chemical reaction.
Enzymes increase the rate of the chemical reactions carried out during metabolism.
Enzymes control all reactions of metabolism .
Enzymes are catalysts. Catalysts speed up reactions between substances.

The endocrine system is responsible for producing enzymes. Hormones released by the endocrine glands stimulate the production of enzymes in various tissues and organs of the body. Enzymes play a crucial role in facilitating chemical reactions within the body, and their production is regulated by the endocrine system.
Enzymes play a crucial role in various biological reactions within the body. They act as catalysts, speeding up chemical reactions that are necessary for processes like digestion, metabolism, and energy production. Without enzymes, these reactions would proceed too slowly to sustain life. Enzymes are also involved in repairing DNA, regulating hormones, and supporting immune function.
A membrane-bound structure that contains digestive enzymes is called a lysosome. Lysosomes play a crucial role in breaking down cellular waste and foreign materials, such as bacteria and cellular debris, into simpler molecules that can be recycled or eliminated from the cell.

Copper is a necessary co-factor for several enzymes. Most of them have to do with energy production.
In the liver, heme is a component of several vital enzymes, particularly cytochrome P450, involved in the metabolism of chemicals, vitamins, fatty acids, and hormones.
Chromium is important in carbohydrate metabolism. Chromium stimulates the activity of enzymes involved in the metabolism of glucose for energy and appears to increase the effectiveness of insulin and its ability to handle glucose, preventing hypoglycemia or Diabetes.
Lysosomes's role in metabolism is digestion.
