Question

At each of the complexes described in the previous question, what also occurs as the free energy is released during electron transport? Why is this important? Describe the components of ATP syntheses. Which parts are static and which parts are mobile? the Binding Change Model for ATP synthesis, as proposed by Paul Boyer, describes how the flow of protons drives the endergonic process of ATP synthesis. Using your knowledge of the structure of ATP syntheses (above) and the different conformations of the beta subunit, describe this model and how we go from electrical energy, to mechanical energy, to chemical energy. How many ATP can be generated from the oxidation of NADH? FADH_2? What is the theoretical ATP yield for aerobic cellular respiration? Why is the yield actually less than this number?

Explanation / Answer

20. ATP synthase is the enzyme that would make ATP from chemiosmosis. That permits protons to pass through the membrane and uses typically the energy significant difference to phosphorylate adenosine diphosphate (ADP) and preparing ATP. Proton-motive force is formed from an electron transport chemical chain which in turn serves simply because a proton pump, with all the electrical power from electrons from an electron carrier, to pump protons out around the membrane, removing typically the charge around the membrane. Around mitochondria, electrical power discharged from the electron transport chemical chain used to safely move protons belonging to the mitochondrial intercellular substance into the mitochondrial intermembrane space. Moving protons out of the mitochondrion results in a lesser attention of positively charged protons inside, causing a bit of an adverse negative charge inside the membrane. A lot of these gradients of negative charge have significant difference with a merged electrochemical gradient all around the membrane, and this is indicated as Proton Motive Force (PMF).
