Methodological and methodical aspects of carbohydrate metabolism study in plant cells as the adjoint system

The choice of the research topic is not accidental. Photosynthesis is the basis of anabolism for plants as well as for all living organisms on Earth, while breathing is the basis of their catabolism. In turn, anabolism and catabolism are the links of metabolism, which determines the vital activity of any type of cells and the whole organism. The paper deals with the methodological potential previously justified by the authors of the conjugation category studying such important physiological and biochemical processes as photosynthesis and respiration. The application of this category by students while developing the concepts of photosynthesis and breathing will equip them by an effective methodological means of knowledge. Reflecting the conjugation category extends the ways we understand the principles of the structural organization of matter as a whole, and opens up new prospects, new approaches to solving the most important problems of science and their role in understanding the structure of rational knowledge. The figurative-sign model developed by the authors will allow to develop more effectively the concepts of photosynthesis, breathing and carbohydrate metabolism as a conjugated system at the theoretical level.
