[单选题]
In chemiosmosis, what is the name of the enee l/5r6q2rmx,m6jhi zym:zi-8 ey ngxog25hsa5e which plays an important role in the diffusion of protons into the zy5-i 2nsghgoa8e 5:xmatrix of the mitochondrion?
A. Cytochrome oxidase
B. Coenzyme FAD +
C. Coenzyme NAD +
D. ATP synthase
参考答案: D
本题详细解析:
Chemiosmosis is the last stage of aerobic cellulareh6ma3 /g1 sf6szyl dnna 9m0ytd,1l2 respiration and is part of oxidative phosphorylation. This is where ATP is synthesized. ATP synthase is the enzyme responsible for the diffusion of protons into the matrix.
Both coenzyme FAD
+
(Choice B) and NAD
+
(Choice C) are known as electron and hydrogen ion carriers which are responsible for electron transport by gaining and losing electrons and hydrogen ions. The movement of electrons in the electron transport chain is a required step in the generation of ATP.
Cytochrome oxidase (Choice A) is the enzyme that is found in the inner mitochondrial membra/a 3dgdlyf102l, a1ne6 sm tzynh9sm 6ne which is responsible for the movement of electrons that would then combine with both oxygen and hydrogen ions to produce water.
