Where in the cell do electron transport chain occur?
In the mitochondria. The complexes need for the electron transport chain are attached on the inner side of the inner mitochondrial membrane, which channels opening into the intermembrane space for pumping out protons.
Where does a Electron Transport Chain happen?
In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.
What happens at the cristae?
The aerobic phase of cellular respiration.
What goes into the electron transport chain?
The electron transport chain is a series of redox reactions( Oxidation-Reduction) in which electrons are passed from carrier molecules down the chain to ultimately form ATP. The electron transport chain is an energy converter, transforming the chemical energy to the energy of a H+ gradient. As electrons flow along the electrochemical gradient, some of the energy is used by each complex to pump H+ ions from the mitochondrial matrix to the inter-membrane space. These Hydrogen ions create the electrochemical proton gradient that drives them back across the inner membrane through the ATP synthase complex. ATP synthase uses energy of H+ flow(electrical energy) to synthesize ATP from ADP and P. Oxidation of each NADH + H to NAD+ yields 3 ATP. Remember that oxidation is the loss of an electron and reduction is the gain of an electron. Ultimately the purpose of Cellular respiration is to make ATP. The electron transport chain carries out oxidative phosphorylation, which accounts for most of the ATP generated by cellular respiration. A phosphate group is tacked onto ADP to make ATP, using the energy formed from the electrochemical gradient. This pathway has much detail, much more than I've spoke of. Oh, and the Krebs cycle( a simplified version) ...During each turn of the cycle, 2 carbon atoms are removed from the substrates as CO2, 4 oxidations by removal of hydrogen atoms occur, producing four molecules of reduced coenzymes( 3 NADH + H+ and 1 FADH2,) and 1 ATP. The reduced coenzymes produced in the Krebs cylcle are the substrates for the Electron transport chain. These are the electron carriers. Finally, we must remember that Oxygen is required for the Krebs cycle and Electron transport chain and is thus, Aerobic.
What are redox half reactions?
A redox half reaction is a reduction or an oxidation reaction. He half reaction does not occur by itself it much be coupled so that he electron released for another to be accepted.
Which reactions of aerobic respiration occur in the inner mitochondrial membranes?
Chemiosmosis and the electron transport chain's process
What reactions occur in the cristae of the mitochondria?
The reactions that occur in the cristae of the mitochondria involve the electron transport chain. It is embedded on the inner membrane of the mitochondria.
What does electron transport chain occur in?
the mitochondria.
Does the light independent reactions of the Calvin cycle occur in the thylakoids?
In photosynthesis, the the electron transport chain is part of the light dependent reactions. The "light independent reactions" are the Calvin-Benson cycle and do not include an electron transport chain, but the Calvin Cycle cannot proceed without the ATP and NADPH produced during the light reactions.
Can the electron transport chain occur without the Krebs cycle?
No
Where do the reactions of the electron transportation chain occur?
In the inner membrane of the mitochondria.
Where in the cell Krebs cycle and electron transport chain occur and whether they are anaerobic or aerobic?
Both the Krebs Cycle and the electron transport chain are in the mitochondria and they are aerobic.
Where do the reactants of the electron transport chain occur?
In the inner membrane of the mitochondrial organelle.
Where in the cell does the electron transport occur?
Mitochondria in animals; the chloroplasts in plants.
Where does the ETC occur in the cell?
the electron transport chain occurs in the matrix of the mitochondria
What are the three processes that occur during cell respiration?
The three major reactions are-Glycolysis-Electron transport chain (ETC)-Krebs Cycle
Where does the citric acid and electron transport chain occur within the?
Within the mitochondria, matrix and the membrane respectively.
