In Both Chloroplasts and mitochondria, the transfer of electrons down the electron transport chain involved hydrogen ions and leads to a similar outcome. Describe the outcome, and explain how it contributes to the productions of ATP in each of these Organelles.

Expert Solution

In chloroplast, the electron transport chain takes place in the thylakoid membrane and transfers the flow of electrons. This flow of electron transport the proton ion to the thylakoid lumen from the stroma. The splitting of water in photosystem 2 also produces proton ion in the thylakoid lumen. This create Proton gradient in the thylakoid lumen. The proton ion is transported back to the stroma through ATPsynthase complex. In this process, the ATP is synthesized from the ADP and inorganic phosphate.

In mitochondria, the electron transport chain takes place in the inner membrane of Mitochondria. The flow of electron takes place in the electron transport chain. Now this flow of electron transport the the proton Ion from the the mitochondrial matrix to the the intermembrane space. Now hydrogen ion gradient created due to the transport of proton ion in the intermembrane space. The backflow of proton from the intermembrane space to the mitochondrial Matrix through complex ATP synthase will synthesise ATP from ADP and inorganic phosphate.

The electron transport chain has two diffusible electron carriers, ubiquinone, which shuttles electrons to the third mitochondrial complex, and cytochrome c, which shuttles electrons to the last mitochondrial complex (see figure below). Would it be possible for cells to use only one of these two diffusible electron carriers to shuttle electrons at each of these two steps of the electron transport chain? Why or why not?
