Chemiosmotic model of atp synthesis - …

and also can use chemiosmosis to generate ATP. , , and create energy by a process called . These bacteria use the energy of light to create a proton gradient using a photosynthetic . Non-photosynthetic bacteria such as E. coli also contain .

Besides, the chemiosmotic theory intermediates involved in the synthesis of ATP.

The Nobel Prize winner Otto Warburg observed that many, and perhaps most, cancer cells derive most of their energy from glycolysis and lactic acid fermentation, even when oxygen is plentiful (see review by Liberti and Locasale, 2016). Several explanations have been proposed. One is that cancer cells can promote biosynthesis and cell growth by NOT respiring organic carbon to CO2, and using the organic carbon to build cellular biomolecules, instead. Another hypothesis is that ramping up glycolysis allows tumor cells to out-compete normal cells or immune system cells for glucose. A third hypothesis is that lactic acid secretion causes changes in the tumor cells’ environment that favors tumor cell growth and spread.

This was a radical proposal at the time, and was not well accepted. The prevailing view was that the energy of electron transfer was stored as a stable high potential intermediate, a chemically more conservative concept.

proposed the chemiosmotic hypothesis in 1961. The theory suggests essentially that most synthesis in cells come from the gradient across the inner membranes of by using the energy of and formed from the breaking down of energy rich molecules such as .

In prokaryotic cells, all the metabolic pathways occur in the cytoplasm, except for chemiosmosis and oxidative phosphorylation, which occur on the plasma membrane. Prokaryotic cells are capable of anaerobic respiration using alternative electron acceptors such as nitrate and sulfate, although they prefer oxygen as the terminal electron acceptor to drive chemiosmotic ATP synthesis. In the absence of any suitable electron acceptor, they use fermentation pathways.

they answer an extra credit question that asks who proposed the theory of synthesis of ATP.

(ATP) synthesis in respiring cells ..

Peter D. Mitchell proposed the chemiosmotic hypothesis in 1961. The theory suggests essentially that most ATP synthesis in respiring cells comes from the electrochemical gradient across the inner membranes of mitochondria by using the energy of NADH and FADH2 formed from the breaking down of energy-rich molecules such as glucose.

Bacteria and archaea also can use chemiosmosis to generate ATP.

Hydrogen ions (protons) will from an area of high proton concentration to an area of lower proton concentration. proposed that an of protons across a membrane could be harnessed to make . He linked this process to , the diffusion of water across a membrane, which is why it is called chemiosmosis.
