In chemiosmosis, what is the name of tc m9dy,dyi9i/ tnjd*4 he b6t c,w (xs6mao+re1n enzyme which plays an important role in the diffusio(oec6bt rxam,1 wn+s6 n 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 last stage of aerobic cellular re+gw p,pds e0:bmx7xj,spiration 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 membrane which is responsible for the movement of electrons that would then combine with bot, 7be+ 0gxmjp:pwd,sxh oxygen and hydrogen ions to produce water.
