The article reveals the content of biochemical concepts constituting school biology course, shows their development during the study of all the units of the subject mentioned above: from the vegetable organism to the general laws of nature. Biology as a school subject is a system of biological concepts, developing in a logical sequence. The handling of the relevant concepts shows the degree of assimilation of biological knowledge. That is why the teachers work on assimilation and development of biological concepts is so important. The study of biochemical concepts is included in the school course of biology. They can be classified according to the nature of the content, along with morphological, anatomical concepts etc. Some biochemical concepts belong to the group of basic biological concepts, i.e. concepts about the biological regularities concerning with the whole wildlife. They are: metabolism and interchange of energy, nutrition, breathing, selection, photosynthesis. A number of biochemical concepts such as proteins, carbohydrates, vitamins, enzymes and some others are special, as they are studied within a specific section. The article analyzes school curricula and textbooks on biology; it allows making a conclusion that biochemical concepts are formed and developed throughout the biology course from 6 to 11 grades. There is a succession in formation and development of these notions: at first they are special and are studied as processes characterizing the functioning of a plant; considering the processes occurring in animal organism, biochemical concepts become general. In the General Biology unit they become special again. Such regularity is substantiated by the logic of construction of biological material. The formation of biochemical concepts is contributed to by all kinds of verbal, visual and practical methods of teaching biology, the role of the latter is particularly important. It requires the use of activity approach during the formation of biochemical concepts, because one of the conditions for their proper formation is the application of knowledge in practice. Skills acquired by students are the indicators of the effectiveness of education, together with the amount of subject knowledge.
