In chemiosmosis, what is the name of the enzyme which pf;sim*/vv1b 57ww aa dlays p *fmvtd3h.9van important role in the diffusion of protons into the matrix otdp93hmf.v v *f 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 cw,z 4c+ a(qt68 dxhbe5mqv0agellular 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 membrane which is res ,ga5 wqc6 ve8xh(+mb0zqtda4ponsible for the movement of electrons that would then combine with both oxygen and hydrogen ions to produce water.
