Identify the missing words in the below description about electron transport chain. Word bank: ATP synthase, electrons, glycolysis, oxidation-reduction, oxidoreductases, protons, proton motive force, TCA cycle, Question: NADH and FADH2 generated from and donate their high energy the first electron acceptor molecule on the ETC. The electron then flow through a series of electron accepting molecules via repeated reaction, releasing some energy at each step. The released energy is captured by the membrane-bound (where the e-accepting molecules are in) and used to pump creating a proton concentration gradient (higher outside of the cell, lower inside the cell) known as the cell via the proton channel on the membrane, the energy is used by the enzyme RH Glycolysis NDH-1 NADH+H TCA cycle 4H¹ 4H Electron transfer is coupled to pumping H+ ions. 2H NAD + 2H* Quinone pool Quinols carry electrons to another ETS complex pumping H* ions. 2H* Mod SIGH 2H 2H* ½20₂ + 2H* Cyt bo to generate ATP from ADP+Pi. outside of the plasma membrane, .

ATP is an important molecule in cellular energetics. Which of the following statements is false? ATP hydrolysis can provide the energy required for mechanical work in a cell. All of the ATP made during cellular respiration is made by the enzyme ATP synthase. ATP synthesis is an endergonic reaction. None of the other answers are false.

Give typing answer with explanation and conclusion

Chemiosmosis is a part of oxidative phosphorylation, the final step in cellular respiration. Which of the following is TRUE regarding chemiosmosis?     ATP synthesis creates a proton gradient that causes electron flow through an electron transport chain (ETC). A temperature gradient drives ATP synthesis. The energy from a proton gradient is used to make ATP. Chemiosmosis regenerates electron carriers like NADH and FADH2.

Explain the electron transport chain. You must know the reactants, products and location for each step.

Which of the below cellular processes requires input of ATP energy? Group of answer choices ATP-synthase creating ATP Na+-K+-ATPase (sodium-potassium pump) activity Simple diffusion Pyruvate Oxidation The Electron Transport Chain

In glycolysis, identify the enzyme and type of reaction (REDOX/group transfer/C-C make it or break it/isomerization/etc) that: -requires energy input form ATP (name one) -reduce NAD+ -are essentially irreversible in the cell (name 2) -is the committed step

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? 20. Because they lose their mitochondria during development, red blood cells cannot perform aerobic respiration; however, they do perform glycolysis in the cytoplasm. Why do all cells need an energy source, and what would happen if glycolysis were blocked in a red blood cell? 21. What is the primary difference between a circular pathway and a linear pathway? 22. How do the roles of ubiquinone and cytochrome c differ from the roles of the other components of the electron transport chain? 23. What accounts for the different number of ATP molecules…
