Answer #1

Answer is : E (C and D).

The oxidative phosphorylation is the process in which ATP is synthesised from ADP via the protin gradient energy.

In this case, the the electron moves from NADH to the oxygen. There is found more reduction potential in subsequent steps. This provides the reduction potential

The inter membrane space has more proton as compared to the matrix. That's why pH gradient is required.

The more the ADP to ATP ratio in the cell, more will be ATP synthesis occur.

Please rate high...

Mitochondria produce most of the cell's ATP by oxidative phosphorylation. Electrons from NADH and FADH2 formed in the TCA cycle are transported through the electron transport chain (ETC) which consists of four complexes (I, II, III and IV). Hereby, a proton gradient is formed across the inner membrane of the mitochondria which is used by the ATP synthase to form ATP. In isolated mitochondria, oxygen consumption rate (OCR) and rate of ATP synthesis can be determined, respectively. Seahorse and NOVOstar...
