2026 選修生物II CH3-2 光合作用的綠色革命-碳反應篇
from 雷比特生物空中講 · host 雷比特老師
詳盡解析光合作用中卡爾文循環的生化機制及其對地球生命的深遠意義。首先將葉綠體基質比作「分子工坊」，拆解了碳固定、還原與起始物再生這三大步驟，特別強調了 RuBisCO 酶在捕捉二氧化碳過程中的核心地位。接著探討植物為了應對乾旱與光呼吸缺陷，演化出 C3、C4 與 CAM 等多樣化的碳固定策略，展現生物演化的生存智慧。最後，文本將視角放大至全球尺度，論述光合作用如何透過大氧化事件重塑大氣環境，並啟發當代科學開發人工光合作用，以應對未來的能源與氣候挑戰。 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://gemini.google.com/share/343441242dc2 Powered by Firstory Hosting
