Question

If each NADH can drive the synthesis of 2.5 ATP. and FADH_2 can drive the synthesis of 1.5 ATP, how many total ATP (or equivalents) are ultimately produced from 1 acetylCoA molecule in the citric acid cycle? 10 9 1 30 0 The water splitting enzyme of photosystem II uses what metal as part of its mechanism? Fe^+3 Ca^+2 Mn^+2 Mg^+2 Sn Uncoupling agents, such as dinitrophenol. make the inner mitochondrial membrane leaky to protons. This results in continued AlP production, but no oxygen consumption no ATP production and no oxygen consumption oxygen consumption, but no ATP production no effect on oxygen or AIP production an increase In NADH concentration Which of the following experimental observations would NOT support the chemiosmotic model of oxidative phosphorylation? If mitochondrial membranes are ruptured, oxidative phosphorylation cannot occur. Raising the pH of the fluid in the intermembrane space results in ATP synthesis in the matrix. Transfer of electrons through the respiratory chain results in formation of a proton gradient across the Inner mitochondrial membrane The orientation of the enzyme complexes of the electron transfer chain results in unidirectional flow of H^+ Radioactively labeled inorganic phosphate is incorporated into cytosolic ATP only in the presence of a H^+ gradient across the inner mitochondrial matrix. Which of the following statements about the resting membrane potential is TRUE? is normally equal to zero volts. The inside of the membrane is positively charged compared to the outside, results, in part, from the concentration gradients for Na^+ and K^+ It is due in part to the presence of extracellular proteins. All of the above are true

Explanation / Answer

One cycle of citric acid :

3 NADH + 1 FADH2 + 1 ATP = 3 x 2.5 + 1 x 1.5 + 1 = 10 molecules of ATP
