protons and electrons

Listing 1 - 8 from 8 for protons and electrons

WATER
... and water are the ingredients - the power for the process comes from the hydrogen in the water. In a sense, water is split, or to be even more precise, the protons and electrons ... electrons in two rings, and eight protons and eight neutrons in its nucleus. Shown here are two - dimensional diagrams for three - dimensional atoms and molecules. All diagrams are from models and the nucleus and electrons ...

... Metabolism ATP and Other Nucleoside Triphosphates or: Bonds Rich in Energy Acceptors of Protons and Electrons (Hydrogen Acceptors) Glycolysis and the Citric Acid Cycle Electron Transport and Oxidative ... of reactions is the uptake of hydrogen (protons and electrons): H2 > 2H+ + 2e-. The most important acceptor of protons and electrons within a cell is nicotinamide adenine dinucleotide (NAD ...

... one of which requires molybdenum as a cofactor. In addition, ATP, Magnesium ions, ferredoxin and protons are required for catalytic activity. ATP provides energy by hydrolysis of high energy ... for ATP hydrolysis. Ferredoxin acts as an electron donor, and protons are required to add hydrogen to nitrogen, forming ammonia. Electrons carried by ferredoxin are provided by NADPH. Recent discoveries have ...

... grew, the need arose to somehow resynthesize complex compounds, both to eat and to use for structure and function. Some organisms learned how to use the sun's energy to ... water into hydrogen and oxygen: H2O + light energy ---> O2 + 2H+ + 2 electrons These electrons travel through the mebrane much like the electrons in oxidative phosphorylation, using their energy to pump protons through the ...

... and is thus sometimes called P-680. Energy enters the system when PS2 becomes excited by light. Electrons are shed by the excited PS2 (oxidation), which grabs electrons ... electrons, and turns right around to reduce its neighbour in the pathway by giving it the electrons, thus becoming reoxidized and ready for the next electrons ... the redox chain, thus pumping protons through the membrane to generate ATP ...

... , and it accepts and transfers one electron at a time. QB is a loosely bound plastoquinone molecule, which accepts two electrons and then takes on two protons, before it detaches and becomes mobile and called ... both electrons and protons (hydrogens). It is a H-atom carrier. At the Cyt bf complex it is then oxidized, but FeS and Cyt b6 can only accept electrons (not protons). So the two protons are ...
