In the diagrams above, an Electron Transport Chain (ETC) was depicted. ETCS contribute to the synthesis of ATP because the enzymes in the ETC O Pump hydrogen ions to the outside of the cell to form a Proton Motive Force that powers ATP Synthase. Allow the recycling of electrons so that they can be recharged and placed onto ATP. O Srip electrons off of an electron donor and place them onto ADP to form ATP. O atalyze substrate level phosphorylation. O Lower the activation energy of ATP synthase, making it more energetically feasible to power the addition of a third phosphate group onto ADP to form ATP.

During glycolysis step 7, ATP synthesis occurs through ______. The energy for this reaction comes _____     oxidative phosphorylation; indirectly from oxidation of NADH/FADH2     Gaining of electron; Hydrolysis of ADP     Reduction of Oxygen; Dissipation of proton gradient     substrate level phosphorylation; coupling directly to an exergonic reaction.

The conversion of ADP + Pi to ATP is an endergonic reaction. The energy to drive the reaction comes from Select an answer and submit.

Choose any/all that apply to the proton-motive force and ATP synthesis. The active pumping of protons through ATP synthase against their concentration gradient provides the energy needed for ATP synthesis. Rotation of the y subunit creates conformational changes in the active sites of ATP synthase that drive the release of ATP from the enzyme. Each 3 subunit of ATP synthase has a distinct amino acid sequence that accounts for the three different active sites present in the enzyme. The ATP molecules produced from the pair of electrons provided by NADH have greater potential energy than the ATP molecules produced from the pair of electrons provided by FADH₂. Inhibition of either ATP synthase or ATP translocase will stop flux through the electron- transport chain.
