Question

What does the chemiosmotic hypothesis claim? What does the chemiosmotic hypothesis claim?a. ATP is generated using a phosphate gradient produced by glycolysis and the citric acid cycle. b.Water is generated using electrons taken from NADHNADH and FADH2FADH2 and transported through the electron transport chain.c. ATP is generated using a proton-motive force that is produced by the electron transport chain. d.ATP is generated using phosphates taken from intermediates in the electron transport chain.

Answer 1

Answer: C

Explanation:

Chemiosmosis couples electron transport chain to ATP synthesis. NADH and FADH shuttle high-energy electrons extracted from food during glycolysis and citric acid cycle to an electron transport chain built into the inner mitochondrial membrane.

In the electron transport chain, electron are transport and pumping of electrons create an H+ gradient across the membrane.

During Chemiosmosis, the protons flow back down their gradient via ATP synthase, which is built into the membrane nearby. The ATP synthase harnesses the proton-motive force to phosphorylate ADP, forming ATP.

Therefore ETC and Chemiosmosis make up oxidative phosphorylation
