F1馬達( F1-ATPase )為一種高效率的旋轉性馬達蛋白,其燃料來自於ATP水解後所釋放的化學能。在實驗環境下,F1馬達被置於充滿ATP的溶液下轉動。轉動過程中F1馬達受到三個作用力影響:黏滯阻力、介質流體的布朗力以及水解ATP 所獲得的驅動力。這三個因素的總和,影響整個F1馬達轉動的情形。
本文以酵素動力學的觀念來模擬F1馬達的轉動,也就是F1馬達的運動表現只考慮受到ATP化學能的影響。文中試圖推論F1馬達在低負載、低阻力情況下的運動表現,並與其它文獻之實驗結果做比較。
結果發現在濃度與轉速的關係圖中,其它文獻之實驗值與本文之理論值曲線具有相同趨勢,這更加驗證了F1馬達是屬於動力衝程模式的運動表現。此外;在推導的過程中也發現,若採用酵素動力學分析,可以得到另一個重要參數 。在本文假設條件下,此參數的應用,對於簡化實驗步驟以及預測F1馬達在低負載情況下的運動表現有顯著的影響。
