蛋白质是人体必需的重要营养成分之一,没有蛋白质就没有生命,如果蛋白质摄入量不足,会使人______、______、______.医疗器械通过高温可以消毒,这是因为______;游泳池里通常放一些胆矾,其目的是______.

答案

蛋白质是构成细胞的基本物质,是机体生长和修补受损组织的主要原料,如果蛋白质摄入量不足,会使人生长发育迟缓,体重减轻,还可能无法合成血红蛋白,造成贫血.

细菌和病毒的主要生命物质是蛋白质,在高温下可以失去生理活性,所以高温可以杀菌;另外,可溶的重金属盐也可使蛋白质变性,所以游泳池里通常放一些胆矾消毒.

故答案为:生长发育迟缓;体重减轻;发生贫血;高温可以使蛋白质变性;重金属盐能使蛋白质变性.
