Concept introduction:
Coupled reactions are the pair of biochemical reactions that occur simultaneously in a system and the energy released by one reaction is utilized by another reaction to occur. Oxidative phosphorylation and oxidation reaction of the electron transport chain is an example of a coupled system.
Oxidative phosphorylation is the biochemical process for the synthesis of ATP from ADP and
Electron transport chain is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule.

- How many ATP will be produced in an oxidative level phosphorylation of a molecule of glucose in a eukaryotic cell?arrow_forwardOther than the half channels in the C-ring, what other transporters use protons during ATP synthesis?arrow_forwardIf actively respiring mitochondria are exposed to an inhibitor of ATP-ADP translocase, the electrontransport chain ceases to operate. Why?arrow_forward
- How much energy is required to pump a mole of protons in a mitochondria with the following conditions? pH of matrix = 8.2, pH of intermembrane space 7.4, membrane potential of - 65 mV (N-side relative to P-side), temperature = 37C. Express answer to the nearest 0.1 kJ/mole.arrow_forwardOnly 37 of the proteins in mitochondria are encoded by the mitochondrial DNA. The other proteins are encoded in nuclear DNA, then translated and transported to the mitochondria. Describe one unique feature of protein transport across mitochondrial membranes.arrow_forwardConsider a 24:1 △cis-9 fatty acid in the mitochondrion. For each fatty acid given, determine the following. Total number of ATP deducted Total net ATParrow_forward
- 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_forwardUsing the answer code on the right, indicate which form of energy production is being described: 1. takes place in the mitochondrial matrix 2. produces H2O as a by-product 3. results in a rich yield of ATP 4. takes place in the cytosol 5. processes acetyl-CoA 6. takes place in the mitochondrial innermembrane cristae 7. converts glucose into two pyruvate molecules 8. uses molecular oxygen 9. accomplished by the electron transport system and ATP synthase (a) glycolysis (b) citric acid cycle (c) oxidative phosphorylationarrow_forwardWhen muscle cells run out of oxygen, what happens to the potential for energy extraction from sugars and what pathways do the cell use?arrow_forward
- In aerobic cellular respiration, which reactions occur only in the cytoplasm? Which ones occur only in a cells mitochondria?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: If the inner mitochondrial membrane were rendered as permeable as the outer membrane, how would that affect oxidative phosphorylation? Which specific processes would stop and which remain?arrow_forwardIdentify the molecules that enter the oxidative-phosphorylation pathway and the products that form.arrow_forward
