2025newtalk 國中生物單元三 : 生物體內代謝的催化劑-酵素enzyme

解釋酵素，是主要由蛋白質組成的生物催化劑，在生命活動中的關鍵作用。它闡述了酵素如何作為「微型工人」加速體內化學反應，同時自身不會被消耗且可重複利用。強調酵素的專一性，即每種酵素僅作用於特定物質，如同「鑰匙與鎖」的配對關係，並指出酵素的最佳作用受溫度和酸鹼度等環境因素影響。總之，酵素是維持身體正常運作、將食物轉化為能量的高效且不可或缺的推手。聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址  https://g.co/gemini/share/0b7d578f59ce  Powered by Firstory Hosting
