1. Which of the following metabolic pathways is common to both aerobic and anaerobic processes of sugar breakdown?
1. 下列哪一個代謝途徑是糖類分解的「有氧」與「無氧」過程中所共有的?

(A) the Krebs cycle (克氏循環/檸檬酸循環): 發生在粒線體,需氧屬有氧呼吸。
(B) the electron transport chain (電子傳遞鏈): 粒線體內膜,需氧屬有氧呼吸。
(C) conversion of pyruvic acid to lactic acid (丙酮酸轉化為乳酸): 屬乳酸發酵,僅在無氧條件下發生。
(D) glycolysis (糖解作用) :(O) 發生於細胞質,不需氧。所有細胞呼吸的第一步,將葡萄糖分解為丙酮酸。
(E) conversion of pyruvic acid to acetyl CoA (丙酮酸轉化為乙醯輔酶 A): 進入克氏循環前的橋接反應,屬有氧路徑。
