- What would be the effect on ATP production during chemiosmosis and oxidative phorphorylation, if the pH within the inner membrane space of the mitochondrion were decreased, assuming no effect of pH on the structure of proteins in the membrane? a) it would increase b) it would decrease c)it would stay the samearrow_forwardDescribe in general terms the structural makeup of a mitochondrion.arrow_forwardAlthough the outer mitochondrial membrane is permeable to all small molecules, the inner mitochondrial membrane is essentially impermeable in the absence of specific transport proteins. Consider this information answer: The ATP generated by oxidative respiration is used throughout the cell. The majority of ATP production occurs in the mitochondrial matrix. How do you think ATP is made accessible to enzymes in the cytosol and other organelles?arrow_forward

- As protons (H+) pass through the mitochondria inner membrane… Question 10 options: a) Protons follow their concentration gradient. b) All the potential energy contained in the proton gradient is converted into ATP. c) Some of the potential energy contained in the proton gradient is converted into ATP and some is released as heat (i.e., unusable energy). d) Protons go up in potential energy level and ∆G > 0. e) A and Carrow_forwardIt has been estimated that mitochondria occupy 20% of the volume in the human body. For a 70- kg adult, the average number of mitochondria has been estimated to be 1 × 10 (10,000 trillion). Using this information, provide a rough estimate of the average mass of a mitochondrion.arrow_forwardYou 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. Which of the following is the best explanation for this observation? F It increases the conc. of OH-, causing the mitochondria to pump H+ to the intermembrane space. 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.arrow_forward
- The glycerol-3-phosphate shuttle can transport cytosolic NADH equivalents into the mitochondrial matrix (see Fig. 15.11c). In this shuttle, the protons and electrons are donated to FAD, which is reduced to FADH₂. These protons and electrons are subsequently donated to coenzyme Q in the electron transport chain. End of Chapter Problem 86a How much ATP is generated per mole of glucose when the glycerol-3-phosphate shuttle is used? (Tolerance is +/- 2%) ATP are generated per glucose.arrow_forwardIs proton concentration higher in the intermembrane space or the matrix of the mitochondria?arrow_forwardFigure 7.11 Dinitrophenol (DNP) is an "uncoupler" that makes the inner mitochondrial membrane "leaky" to protons. It was used until 1938 as a weight- loss drug. What effect would you expect DNP to have on the change in pH across the inner mitochondrial membrane? Why do you think this might be an effective weight-loss drug? Intermembrane space Mitochondrial matrix ATP Synthase ADP Inner mitochondrial membrane ATP Figure 7.11 ATP synthase is a complex, molecular machine that uses a proton (H) gradient to form ATP from ADP and inorganic phosphate (Pi).
