Thanks to enzymes, all biochemical reactions in the organic world occur in a certain order, in certain places of cellular biosystems and at a certain speed (far exceeding the speed of the catalysts in the reactions of the inorganic world). One of the main features of enzymes is the ability to directed and regulated action, due to which the coordination of all metabolic links is controlled and implemented – the synthesis of biomolecules and the release of the energy necessary for these processes.
Coenzymes do not participate in chemical reactions, but they contribute to the flow of vital processes, because they transfer atoms or groups of atoms from one reaction to another.
Vitamins are not a material for biosynthesis or an energy source, but they participate in almost all biochemical and physiological metabolic processes in the cell, binding to enzymes.
Hormones also play an important regulatory role in the cellular processes of life. These are humoral factors of influence (and control) on all types of biochemical reactions, especially biosynthesis. They regulate the activity of enzymes in very low concentrations.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
