How do the mitochondria in brown fat offset ATP production in favor of heat generation? O They prevent the formation of the proton gradient across the inner membrane. O They quickly pump protons across the inner membrane. O They prevent the formation of the proton gradient across the outer membrane. O They supply more oxygen to serve as a terminal electron acceptor during respiration.

If actively respiring mitochondria are exposed to an inhibitor of ATP-ADP translocase, the electrontransport chain ceases to operate. Why?
The energy of electron transport (by the ETC) serves to move protons (hydrogen ions, or H") to the intermembrane space of the mitochondrion. How does this help the mitochondrion produce ATP? O This movement of protons sets up the electrochemical gradient that drives ATP synthesis in the mitochondrion. O The protons receive electrons from the NAD+ and FAD that were accepted in glycolysis ad the citric acid cycle O The protons are transferred to oxygen in an energy-releasing reaction O The protons pick up electrons from the electron transport chain on their way through the inner mitochondrial membrane
In the presence of excess oxygen, a complete oxidation of seven molecules of glucose into carbon dioxide and water, by a yeast cell, would produce approximately ATP molecules via oxidative phosphorylation only. (Consider NADH = 3 ATP and FADH2 = 2 ATP)

You are studying the process of oxidative phosphorylation in the lab. You isolate several mitochondria from cells and place them in a buffered solution with a low pH and observe that the mitochondria begin to synthesize ATP.

It increases the diffusion of H+ from the mitochondrial matrix to the intermembrane space. It increases the diffusion of H+ from the intermembrane space to the matrix. It increases the conc. of OH- in the mitochondrial matrix.
