(select all that apply) OEnsure the amount of oxygen being brought in is appropriate for cell health OMaintain cell components at appropriate levels OConserve materials Ensure efficient use of energy stores Question 49arrow_forwardWhen muscles contract, a chain of events result in greater activity by the TCA cycle. All of the following are links in that chain EXCEPT: The ADP concentration increases. Rate of respiration and oxygen consumption increases. The electron transport chain produces more water. The concentration of NADH decreases and the concentration of NAD+ increases. 2) (True or False )______The concentration of oxaloacetate drops and TCA cycle is halted which leads to the synthesis of ketone bodies. 3) NADPH is used for: a) Oxidizing vitamin E b) Oxidizing glutathione c) Reductive biosynthesis of fatty acids d) β-oxidation of fatty acidsarrow_forwardChoose 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.arrow_forward
