本课围绕高考英语"科普说明文阅读"专题,通过10篇原创英文科普短文训练学生对概念、过程、因果关系、证据和术语语境含义的理解。短文涵盖生物荧光、光合作用、温室效应、菌根真菌共生关系、水循环阶段、板块构造、抗生素耐药性、先天与适应性免疫、动能公式及固氮作用等基础且可验证的科学事实。训练学生根据文本明确信息判断酶的催化作用、区分光合作用的输入与输出物质、理解温室气体吸收再辐射热量的机制、按顺序排列水循环阶段,以及运用动能公式 Ek=½mv² 计算速度变化对动能的影响。配套12张知识点闪卡整理核心科学术语与公式,帮助学生提升英语科普文本的信息定位与逻辑推理能力。
本练习以生物发光、光合作用、温室效应、菌根共生、水循环、板块构造、抗生素耐药性、免疫、动能和固氮等科普短文为材料,训练对概念、过程顺序、因果关系和术语语境含义的理解。
Read the following text: 'Bioluminescence is a natural phenomenon where living organisms produce light through a chemical reaction. This process typically involves a light-emitting molecule called luciferin and an enzyme known as luciferase. When oxygen reacts with luciferin, catalyzed by luciferase, energy is released in the form of light.' Based on the text, what is the primary role of luciferase in bioluminescence?
It functions as a catalyst to facilitate the chemical process
The text explicitly states that the reaction is 'catalyzed by luciferase', which defines its role as a catalyst that speeds up or enables the chemical reaction between luciferin and oxygen.
