2025 biology talkshow:美食的化學轉生-消化腺合作的奧秘

from 雷比特生物空中講 · host 雷比特老師

提供了一篇關於人體消化腺功能的詳細概論,將消化過程比喻為一場精密的「化學轉生之旅」和「美食加工生產線」。依序介紹五個主要的消化腺體及其作用,包括唾腺分泌唾液澱粉酶進行初步分解與潤滑;胃腺分泌鹽酸和胃蛋白酶,在強酸環境中開始消化蛋白質;肝臟與膽囊負責製造與濃縮膽汁,對脂肪進行乳化;胰臟則被譽為「酶王」,分泌含有重碳酸鹽和多種消化酶的胰液,中和胃酸並分解所有主要營養素;最後,腸腺及其刷狀緣酶負責將所有食物分子精細切割成可被細胞吸收的最小單體。總體而言,強調這些腺體在神經與激素(如胰泌素和膽囊收縮素)的精確調控下,進行協同作業,確保營養物質被有效吸收。 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   Powered by Firstory Hosting
