Figure 4.15 Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease? What affect would cyanide have on ATP synthesis? Figure 4.15 (a) The electron transport chain is a set of molecules that supports a series of oxidation-reduction reactions. (b) ATP synthase is a complex, molecular machine that uses an H+ gradient to regenerate ATP from ADP. (c) Chemiosmosis relies on the potential energy provided by the H+ gradient across the membrane.
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.
During chemiosmosis, ATP synthase ____________________. Select all that apply produces ATP in the mitochondrial matrix allows H+ to cross the inner membrane via facilitated diffusion generates water from oxygen and electrons in the mitochondrial matrix pumps H+ against its concentration gradient into the intermembrane space
Draw and label a lipid bilayer containing the large mitochondrial trans-membrane protein complexes representing complex I, II, III, and IV, and ATP Synthase. Label your diagrams with the correct names for the membranes, Make two more of these drawings. Label the first one mitochondrial electron source and using a different ink color, indicate the source(s) of electrons. Label the second mitochondrial energy source, and indicate the source of energy driving the electron transport chain. In the third, label the mitochondrial electron acceptor in its proper position. Also include ATP synthase (in its correct orientation-the spherical part is on the opposite side of the membrane as the H+ reservoir). Use a different color of ink to show where the protons (H+) are pumped to drive ATP synthesis. also indicate where ATP is generated and were the power is stored to generate ATP. NOW, do the same thing with chloroplasts. Draw and label a lipid bilayer containing the large photosynthetic…

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 matrix

Fill in the blanks using the following words/acronyms: protons; Electron Transport Chain; oxygen; inner; Cytochrome c; NADH; ATP synthase; shuttle; ATP (note: the same word/acronym may be used more than one time) Complex I transfers electrons from to Coenzyme Q; and this transfer leads to the extrusion of from the mitochondrial matrix to the outside face of the mitochondrial membrane. Complex II allows the transfer of electrons from succinate to Coenzyme Q. Coenzyme Q is an electron which transfers electrons to Complex III. Electrons transfer from Complex III is associated with translocation. These electrons are then accepted by ; which transfers them to Complex IV. are also translocated at the level of Complex IV during electrons transfer; allowing the reduction of the final electron acceptor of the which is . ll the translocated are then channeled through the pore of the ; providing the driving force for release from the Enzyme complex.
