This mechanism links the gradual oxidation of electron donors in the electron transport chain to the pumping of protons through the membrane, generating the electrochemical gradient required for ...

Oxygen was taken up by both intact and broken chloroplasts when catalase was poisoned. In confirmation of other work we found that oxygen enters the electron transport chain of isolated chloroplasts ...

Researchers advocate ‘rewriting’ of textbooks on electron transport chain in mitochondria A paper by scientists affiliated with the University of São Paulo highlights new discoveries ...

Photosynthetic Electron Transport Chain: A series of complexes and mobile carriers in the thylakoid membrane that transfer electrons to drive the production of energy-rich molecules.

At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this ...

Cultures of the blue-green alga, Aphanocapsa, were grown under iron-limiting conditions and changes in concentration of redox components of the photosynthetic electron transport chain, particularly ...

Mitochondria are the cell’s power plants and produce the majority of a cell’s energy needs through an electrochemical process called electron transport chain coupled to another process known as ...

Many cells can use oxygen or nutrients to generate fuel, and the process is similar in many organisms that use an electron transport chain. But scientists have found that in a tiny organism, things ...

Often called the "energy currency" of cells, adenosine triphosphate (ATP) is produced in mitochondria by oxidative phosphorylation, a process of energy transfer driven by electron and proton ...
