2026 biology talkshow:細胞的防彈衣：「細胞壁牆體材料」的化學分析
from 雷比特生物空中講 · host 雷比特老師
將不同生物的細胞壁比擬為精密的建築工程，深入探討了植物、細菌、真菌與古菌如何運用獨特的化學分子來應對滲透壓與生存環境的挑戰。植物利用纖維素與果膠構築如鋼筋混凝土般的複合結構，細菌則透過肽聚醣交織成網狀的分子防彈衣，而真菌則選用具韌性的幾丁質作為骨架。最令人驚嘆的是，古菌藉由改變分子連結方式形成偽肽聚醣，成功抵禦環境中的化學攻擊。全文旨在闡明結構決定功能的演化邏輯，揭示大自然如何透過微小的化學鍵轉變，創造出多樣且強大的生物防禦機制。 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/df3c53a95cf8 Powered by Firstory Hosting
