Abstract There are two correct answers to the 8th question in chemistry paper of the national college entrance examination 2018 (National Volume I), resulting in a wide range of disputes in the society, in essence, it is a dispute on the concept definition of "enzyme" in the textbooks. Taking the senior high school chemistry textbooks of the People's Education Press as an example, this paper analyzed the concept definition types and characteristics in the textbooks. It was found that there were rich concept definition types in the textbooks, but the definition type of the same concept was relatively simple, which led to the unclear connotation or extension of some concepts, and it was an important reason for the dispute. Secondly, in terms of the relationship between the concept definition type and the course topic content, the concept of "enzyme" in the textbooks was essentially an introduction to the function and effect of a class of protein like enzyme instead of the composition of enzyme. As a result, it could not be judged unilaterally that there were some errors in the concept of "enzyme" in the textbooks. Finally, this paper put forward some suggestions for the expression of concept in the textbooks as well as the teaching of teachers.
