Through the teaching of biological concepts, training students to analyze and inductive thinking, to help improve biological teaching and make students better grasp biological concepts, without rote memorization!<br>Concept is the basis of thinking, students only a large number of master the concept, and then through their own analysis and understanding, in order to make the development of thinking. In the teaching of biological concepts, teachers should not follow the book, but create situations, display phenomena, guide students to make their own summary of the concept, so that students can develop their inductive thinking. For example, a high school biology must be a "molecule and cell" Chapter V, section III, "atP's primary source --- cell respiration", requiring students to define the concept of anaerobic breathing. Because we first talked about aerobic respiration, aerobic breathing content includes: 1. reaction substrate - glucose; 2. reaction condition - reaction process with oxygen involved; 3. reaction is an enzymatic reaction - requires a variety of enzymes to coordinate the completion; 4. oxidation decomposition reaction - complete oxidation decomposition; 5. the product of the reaction - carbon dioxide and water; 6. Release of a large amount of energy - generating a large amount of ATP. We can guide students to analyze the process of anaerobic respiration: 1. reaction substrate - glucose; 2. Reaction conditions - reaction processes without oxygen involvement; 3. Reactionisey reaction - different genesis with the participation of different enzymes; 4. oxidation decomposition reaction - incomplete oxidation decomposition; 5. The product of the reaction - carbon dioxide and alcohol or lactic acid; Release a small amount of energy. Thus, students through analysis and comparison can be summed up the concept of anaerobic breathing: oxygen-free breathing refers to the cell in the absence of oxygen participation, through the catalytic action of a variety of enzymes, glucose and other organic matter is not completely oxidized decomposition, the production of simple organic matter, release energy, the generation of a small amount of ATP process.
