Yeast cells are the simplest unicellular microorganisms belonging to the kingdom of fungi, are a convenient model for studying the biological activity characteristic of yeast cell culture, have low virulence and are used in the food industry, which means they are not dangerous to humans. The article presents the results of a study of the biological activity of the fast-acting yeast Saccharomyces cerevisiae by the photometric method using distilled water and nutrient media - 3% solutions of glucose and sugar. This study formed the basis for laboratory work in the discipline "General and Medical Biophysics" for students in the specialty "Medical Biochemistry" (30.05.01). The study of the biological activity of yeast can be studied as a model of the multiplication of yeast cultures of cells of the Saccharomycetes class, in particular, Candida albicans, the causative agent of human opportunistic infection. The future biochemist is imbued with the possibility of using the physical method for the study of biological objects (yeast), which increases the scientific level of work. The acquired knowledge is necessary in areas of professional activity such as clinical and laboratory diagnostics, medical and biochemical research.
