4、大多数酶的化学本质是蛋白质的化学本质是蛋白质(合成酶的场所主要是核糖体合成酶的场所主要是核糖体,水解酶的酶是蛋白酶水解酶的酶是蛋白酶),也有也有的是的是RNA。2、酶促反应、酶促反应:酶所催化的反应。酶所催化的反应。3、底物、底物:酶催化作用中的反应物叫做底物。酶催化作用中的反应物叫做底物。语句语句:1、酶的发现、酶的发现:、1783年年,意大利科学家斯巴兰让尼用实验证明意大利科学家斯巴兰让尼用实验证明:胃具有化胃具有化学性消化的作用学性消化的作用;、1836年年,德国科学家施旺从胃液中提取了胃蛋白酶德国科学家施旺从胃液中提取了胃蛋白酶;、1926年年,美国科学家萨姆纳通过化学实验证明脲酶是一

6、酶需要适宜的温度和pH值等条件值等条件:在最在最适宜的温度和适宜的温度和pH下下,酶的活性最高。温度和酶的活性最高。温度和pH偏高和偏低偏高和偏低,酶的活性都会明显酶的活性都会明显降低。原因是过酸、过碱和高温降低。原因是过酸、过碱和高温,都能使酶分子都能使酶分子make me happykeep secrets for me share my joyplay with melisten to me and understand mehelp me with my study stay with me when I feel unhappy or bored Friends can:P9 B1T
