Answer #1

Option C is correct

option C: Oxidative phosphorylation requires high energy electrons from the NADH to keep going whereas photophosphorylation obtains electrons from the photolysis of the water to keep going.

In both the cases ATP synthase is used to generate ATP molecules via chemiosmosis.

In both the cases electrons move through various small electron carriers forming a electron transport chain.

In both the cases an intact membrane is required to generate a proton gradient.

One of the "Essential Skills" of our 10th lecture (Photosynthesis) was - "be able to compare/contrast the processes of oxidative phosphorylation in the mitochondrion and the light-dependent reactions in the chloroplasts (follow the energy and electrons in both)." Focus your attention on the electron transport chain in mitochondria and the photosystems in chloroplasts. Both of these involve electron carriers (NADH or NADPH) and both are coupled to ATP synthesis somehow. With a focus on the energy and electrons, describe the...

Electron transport translocates protons across the mitochondrial membrane, establishing a pH gradient. During oxidative phosphorylation by a suspension of liver mitochondria in a medium of pH 7.4, the pH of the matrix was measured as 7.7 and the membrane potential as 0.17 V. Calculate the [H+ ] in the external medium and in the matrix under these conditions. What is the outside : inside ratio of [H+ ]? Under the conditions listed, what is the free energy for the movement...

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...
