细胞呼吸(有氧呼吸和产酒精的无氧呼吸)消耗葡萄糖量的计算是高中生物教学的难点,是必须要掌握的内容,一般的解题思路是写出反应式设未知数,费时较多,而有些学生无法写出反应式,只能放弃。不记反应式、不设未知数是否可以计算呢?可以使用简化公式。一、公式的提出细胞在进行呼吸时,如果产生的CO2量(体积单位,以下所述O2量和CO2量都为体积单位)与消耗的O2量不相等,则说明存在有氧呼吸和产酒精的无氧呼
Cell respiration (aerobic respiration and alcohol-producing anaerobic respiration) Calculating the amount of glucose consumed in high school biology teaching difficult, it is necessary to grasp the content of the general problem-solving idea is to write the reaction set the unknown, more time-consuming, Some students can not write a response, can only give up. Do not remember the reaction, whether the unknown can be calculated? Can use the simplified formula. First, the formula put forward When cells are breathing, if the amount of CO2 produced (volume units, the amount of O2 and CO2 volume units are described below) and consumption of O2 is not equal, indicating the presence of aerobic respiration and alcohol production Anaerobic call
