What does the electron transport chain produce? (Hint: not directly ATP, think about the proton gradient) What function does this product serve in cellular respiration?

Oxygen is the final electron acceptor in the electron transport chain. However, in the absence of oxygen the Kreb’s cycle does not work either. Why does the Kreb cycle not proceed without oxygen when oxygen plays no direct part in its sequence of biochemical reactions? Hint: think of oxidation and reduction of electron carriers.

What compounds are the immediate source of the "high energy electrons" that enter the electron transport system of mitochondria? Where do these electron-donating compounds gain their electrons? What type of compounds are these electron-donating compounds?

What is the carrier molecule in the electron Transport chain (in Cellular Respiration)

For Glycolysis what are steps of cellular respiration for both aerobic (oxygen present) and anaerobic (without oxygen) respiration.  what are the Inputs and Outputs: Clearly indicate the key substrates, intermediates, and products at each stage. Location: Show where this stage of cellular respiration occurs within the cell (e.g., cytoplasm, mitochondria). Energy Production: Highlight the ATP and NADH production at this stage. Oxygen: Show where oxygen is used in the process (e.g., ETC) and where carbon dioxide is produced. Electron Carriers: Indicate the role of electron carriers such as NAD+ and FAD in transferring eleDiagrams: Use diagrams or icons to represent the structures and molecules involved, such as the mitochondria, glucose, ATP, and oxygen. Key Information like important facts or formulas relevant to cellular respiration, like the chemical equations for each stage.

Remember that the chemical energy stored in glucose is found in the chemical bonds. Explain why aerobic cellular respiration releases much more energy for the cell to use than anaerobic. anaerobic cellular respiration examples Lactic Acid Fermentation 20,H,O, + 2 ATP Alcohol Fermentation 2C,H,OH + 2CO, + 2 ATP aerobic respiration tv Aa MacBook Air 80 888 DII DD F2 F3 F5 F7 F8 F9 F10 F11 23 $ & * 3 4 5 7 8 E R Y U { D K L C V M .. .-

Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease? What effect would cyanide have on ATP synthesis?

Explain what are the main differences in the cellular location of the sets of chemical reactions known as aerobic catabolism. How and why are the electron transport chain and oxidative phosphorylation coupled?
