1) Summarize how the electron transport chain functions to produce ATP in a bacterial cell versus a eukaryotic cell. Explain whether or not the term chemiosmosis accurately illustrates this process.
.In bacteria there are several different electron donors and several different electron acceptors. the donor may be NADH or succinate, in which case electrons enter the electron transport chain via NADH dehydrogenase (similar to Complex I in mitochondria) or succinate dehydrogenase. in eukaryotes, NADH is electron donor and electron acceptor is molecular oxygen.
.Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis. so chemiosmosis accurately illustrates this process

Explain how the electron transport chain functions to generate ATP in terms of... electron carriers, oxygen as the electron acceptor, the four inner membrane proteins, the hydrogen concentration gradient, water (H20), and ATP synthase NOTE: I asked this question earlier and unfortunately the answer was too complicated for me to understand, so here I am asking it again. I know this is a huge complicated question if you answer it thoroughly, but if you could please try to keep it...

In the electron transport chain, what provides the energy to produce the molecule of ATP at the end of the chain? The entry of H+ ions into the intermembrane space of the mitochondrion Oxidation of lactate to produce pyruvate NAD+ being converted to NADH + H+ The return of H+ ions from the intermembrane space of the mitochondrion
6. Regarding Ox Phos. What enzymes are involved in the electron transport chain? What enzyme is involved Phosphorylation? How are these two distinct parts of Ox phos interconnected and explain in your own words? (Hint: chemiosmosis) ATP ADP + P ATP synthase e electron-transport
The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain Choose all that apply. Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. Electron carriers in the ETC include ubiquinone...

If you say "no", then identify the specific step of glycolysis (draw it) that requires NAD. (c) During aerobic respiration, NAD* is regenerated when NADH donates its H atom to the electron transport chain. Explain how NAD is regenerated during fermentation. (d)...
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...
