(A) 3
(B) 4
(C) 5
(D) 6
(E) 7

Iron-sulfur protein – electron flow from FMNH2 to coenzyme Q
正確，鐵硫蛋白參與電子傳遞，將FMNH2的電子傳遞到CoQ

Coenzyme Q – lipid soluble electron carrier
正確，CoQ是一個脂溶性的電子載體，參與粒線體呼吸鏈

Cytochrome c – accepts electrons from complex IV
錯誤，細胞色素c接受的是來自複合體III的電子，而非複合體IV

Flavin mononucleotide – accepts electron from NADH in complex I
正確，FMN在複合體I中接受來自NADH的電子

Q cycle – funnels electrons from a 2-electron carrier to a 1-electron carrier
正確，Q循環將來自二電子載體的電子轉換為單電子載體

Catalase – converts reactive oxygen species into hydrogen peroxide
錯誤，Catalase將過氧化氫轉化為水和氧氣，而不是將ROS轉化為過氧化氫

Proton-motive force – hydrolysis of ATP
錯誤，質子驅動力是推動ATP合成的力量，而不是ATP的水解
