The Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation? (Assume that the CF1CF0-ATP synthase yields 3 ATP/14 H+.)

Give all the reactions that will produce ATP either by substrate-level phosphorylation (SLP) or by oxidative phosphorylation (OP). If the given require a shuttle system, please indicate both MA shuttle and GP shuttle and give the ATP produced. Given: glucose 6-phosphate to 2succinly CoA
What is the difference in ATP yield per glucose molecule between the malate-aspartate shuttle and the glycerophosphate shuttle? Hint: Consider electron carriers produced in glycolysis per glucose, the number of protons pumped as a result of the electron entry to the ETC, and the number of cytosolic ATP produced. Enter numeric value only.

Which of the following statements concerning oxidative phosphorylation is false? Group of answer choices: The electron transport chain generates an electrochemical gradient that drives the production of ATP. ATP synthase with fewer subunits in its c ring will produce more ATP per proton. A “loose” β subunit of ATP synthase becomes a “tight” site as it produces ATP. When the supply of NADH and QH2 (ubiquinol) decreases, ATP synthase produces more ATP.
Choose all of the following true statements. Hint: 6 statements are true. □ If an electron moves from an atom of higher electronegativity to an atom with lower electronegativity, energy is released. O Glycolysis occurs with or without oxygen present. Other biomolecules such as lipids, disaccharides, and proteins can enter the biochemical pathway of aerobic respiration just not directly into the first step of glycolysis. Molecules other than glucose can be broken down and used to build up ATP in aerobic respiration. Glycolysis occurs during both alcohol and lactic acid fermentation, producing 2 net ATP. The higher the electronegativity of an atom, the tighter it holds an electron and the lower its potential energy. Water is the final electron acceptor of the ETC in aerobic respiration. Each protein component of the ETC in aerobic respiration is more electronegative than the last.
