1. Where, specifically, is the Electron Transport Chain (ETC) of cellular respiration located within the cell?
2. What do the “taxi” molecules from glycolysis and the citric acid cycle do with their electrons when they reach the ETC?
3. What happens, physically, to the electrons in the electron transport chain? 4. What happens, in terms of energy, as electrons move through the electron transport chain?
1) The ETC is located in the lining of the inner mitochondrial membrane.
2) The taxi molecules transfer the electrons to the ETC.
3) The electrons get transferred from electron donor to the electron acceptor. They flow along the ETC.
4) As electrons move through the ETC, energy is released which is used to create proton gradient by pumping the protons across the membrane. This gradient is then utilized to synthesize ATP.

From which of these phases of cellular respiration does the cell get the most ATP? glycolysis citric acid cycle transition reaction electron transport chain
Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...

Amino acids can enter cell respiration at which stages? electron transport chain glycolysis chemiosmosis citric acid cycle Which signalling system would used to send signals across the entire body? endocrine signaling paracrine signaling synaptic signaling cell-cell recognition cell junction
The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...
