What is common and how are glycolysis and respiration different?

Respiration occupies an exceptional position among other physiological processes. Oxidative respiration is common to all multicellular living organisms, both plant and animal. A number of prokaryotic species also lead this process. Therefore, the main stages of respiration are the same for all living organisms that receive energy using this method.
Respiration is a key metabolic process of any organism for two reasons: when breathing, the chemical energy of organic substances used as respiratory material is released. The exothermic reactions of the respiratory process are directly related to the endothermic processes of cell metabolism and serve as a source of energy for them. Thus, breathing provides the possibility of the flow of endothermic metabolic reactions, the processes of formation of structures and the implementation of movements, which requires energy, breathing undergoes such chemical transformations as a result of which highly active compounds are formed that have great reactivity and play an exceptional role in the metabolism of the body .
Glycolysis is the first step in the decomposition of glucose, that is, a complex organic substance (six-carbon compound) to pyruvic acid, that is, a simpler organic substance (three-carbon compound). Glucose, in turn, is formed either from poly – or oligosaccharides, or from amino acids, or from fats.

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.
