In chemiosmosis, what is the name of the enu qj*rp:t ;.xfzyme which ca2v 01m fdz6* mht3buplays an important role in the hvd62fbzmac t10 m*u3diffusion of protons into the matrix 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 l93 .p,laqmrlr-h.u mnast stage of aerobic cellular 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 B9.u,mm rpn .3-alrqhl) 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 membrane which is responsible for the movement of electrons that would then combine with both oxygen and hydrogen ions to produce water.
