Which is the correct link between conformation of the beta-subunit of the F1 component of the ATP synthase and ADP+P¡ or ATP? loose Binding Change Mechanism binding ATP ADP+P ATP Crepeat ADP ADP +P; ATP ATP +P; tight binding open ATP loose => binding ADP+Pi open => catalyzes ADP+P¡ into ATP tight => releases ATP open => releases ADP+P¡
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.
The image below shows part of a key catabolic pathway. If an individual had a deficiency for the enzyme required at point "X", would they still be able to produce a high rate of ATP during very strenuous exercise? ATP in Glucose Prep. phase Payoff phase ļ - MacRoc Pyruvate →→→ Anaerobic fate of pyruvate ATP out ▬OD OF 1- HP 01 -- Select one: O a. No, because NAD* will not be regenerated by lactate dehydrogenase. The reduction of NAD+ to NADH is a required step during the payoff phase of glycolysis. O b. No, because lactate dehydrogenase is required for the continued recycling of NAD+ to NADH, thus allowing glycolysis to continue. Oc. Yes, because pyruvate dehydrogenase is necessary to produce acetyl-CoA, which under these conditions will feed into the citric acid cycle. Od. Yes, because this enzyme is responsible for the substrate-level phosphorylation necessary to maintain the ATP input for the preparatory phase of glycolysis.

Which statement about the complete oxidation of triglycerides to CO2 and water and the oxidation of glucose to CO, and water is true? C They are both endergonic. Glucose oxidation and triglyceride oxidation use glycolysis. Both generate the same ratio of moles of ATP per mole of fuel molecule oxidized. ATP is hydrolyzed at some point in both pathways.
