- Cyanide is a toxic substance. Cyanide is a cytochrome coxidase enzyme that is competitive. The last enzyme of the electron transport chain in mitochondria is cytochrome c oxidase. One of the most common substrates for cytochrome c oxidase is oxygen. Would an increase in the concentration of oxygen affect the inhibitioncaused by cyanide? How would conditions in the mitochondrial intermembrane spacechange if cytochrome c oxidase and the electron transport chain are notfunctioning properly. .Explain why this change in conditions will be harmful to a cell.arrow_forwardThe Fo subunit of the ATP synthase is present in the ______ while the F1 subunit is in the ____. inner mitochondrial membrane; inner mitochondrial membrane mitochondrial matrix; inner mitochondrial membrane mitochondrial matrix; mitochondrial matrix Inner mitochondrial membrane; mitochondrial matrixarrow_forwardDuring cellular respiration, which of the following diffuses through ATP synthase? O Phosphates O Protons (H* ions) O ATP O Electrons O Carbon dioxide (CO2)arrow_forward
- There are many things that need to be brought into and out of the cell for cellular respiration. When you look at cellular membranes, including the mitochondrial membrane you can find transporters for many of these things, including glucose and ATP. However, we never find transporters for Oxygen (O2) or Carbon Dioxide (CO2). Why would the cell not require transporters for these molecules?arrow_forwardATP synthase attaches a phosphate group to ADP, forming ATP .This process requires energy. The energy is provided by electron carrier molecules in the electron transport system that pump ___________into the intermembrane space (also called outer compartment). When these move back into the ___________, they must move through ATP synthase. This movement through ATP synthase provides the power needed by ATP synthase to push the third phosphate group onto ADP. protons (H+ ions); mitochondrial matrix protons; intermembrane space electrons; intermembrance space electrons; mitochondrial matrixarrow_forwardMitochondria are bounded by a double membrane. The inner filled space is called the matrix, which contains _____ that break down carbohydrate products, releasing _____ to be used for ATP production.arrow_forward
- The inner mitochondrial membrane normally O is virtually impermeable to hydrogen ions (protons). encompasses the F1 subunit of the ATP synthase. is permeable to NADH and NAD+. contains enzymes responsible for two of the chemical reactions that take place as part of glycolysis.arrow_forwardThe electron transport chain is a series of protein complexes that are located in the ________ of a mitochondrion. The protein complexes of the electron transport chain use ________ for fuel. As the electron transport chain runs, it sets up a __________. The name of the molecule that spins like a turbine to generate mechanical energy for making ATP is ___________.arrow_forwardWould you mind explaining the Electron Transport System how you understand it? Explanation: The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. Question: Respond to the Explanation post above about the electron transport chain.arrow_forward
- ADP and inorganic phosphate are provided for oxidative phosphorylation via an: ADP-ATP antiport and a proton-phosphate symport in the inner mitochondrial membrane. ADP-ATP antiport and a proton-phosphate symport in the outer mitochondrial membrane. O ADP-ATP antiport in the inner mitochondrial membrane and a phosphate uniport in the mitochondrial intermembrane space. ADP-phosphate symport in the inner mitochondrial membrane.arrow_forwardWhich of the following statements is most correct? The electron transport chain - A: generates a pH gradient that reduces O2 to H2O B: generates a proton gradient across the outer mito membrane C: generates a proton gradient across the inner mito membrane D: uses the energy stored in high energy electron carriers to synthesize ATP E: establishes a membrane potential across the outer mito membranearrow_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).
