呼吸是为人体和所有其他生命提供能量的化学过程 : 细胞的生长和修復、肌肉收缩、蛋白质的合成、神经的传道和运输中分子的吸收等等。 它发生在所有的活细胞中，不仅是动物细胞，植物细胞也是如此。 有两种呼吸方式 : 有氧呼吸和无氧呼吸。有氧呼吸指 : 有空气参与，因此需要氧气，而无氧呼吸则不需要。 有氧呼吸通过分解食物的热量，在氧气的作用下向细胞释放能量。用这个简化的公式表示:葡萄糖+氧气 ----- 二氧化碳+水+能量。 葡萄糖会被氧气分解，并释放出副产品二氧化碳和水。能量会释放后，产生一种特殊的能量分子，即ATP(三磷酸腺苷)。在ATP的帮助下，能量会被储存在身体内，供以后使用。有氧呼吸在所有细胞中不断发生，通常在线粒体中进行。 点击这里查看更多视频：https://alugha.com/FuseSchool
