nicotinamide adenine dinucleotide phosphate (reduced)
oxidase (in both type of phagocytes)
myeloperoxidase (in neutrophils only)
Strong oxidants like the various ROS can damage other molecules and the cell structures of which they are a part.
NADPH is the reduced form of NADP+, and NADP+ is the oxidized form of NADPH.
 In plants ...
is the source of electrons for glucose biosynthesis.
ATP is the energy source for glucose biosynthesis.
NADPH, an electron acceptor, provides reducing power via energized electrons to the Calvin cycle.
Water is split in the process, and O2 is released as a by-product.
The and ATP generated in the light reactions enter the stroma, where they participate in the dark reactions.
The NADPH is the main reducing agent in cells, providing a source of energetic electrons to other reactions. This leaves chlorophyll with a deficit of electrons, which must be obtained from some other reducing agent.
Making : Once the electron leaves the transport system, it enters another photosystem where it is re-energized by the absorption of another photon of light.
NADP+ + 2H -- NADPH + H+
NADP+ is similar to NAD+ in that it can carry two electrons. One of the electrons is contained within a hydrogen atom, the other is removed from a hydrogen atom and the remaining proton is released..
The electrons from the electron transport chain combine with these H+ ions and nicotinamide adenine dinucleotide phosphate ions (NADP+) to form adenosine triphosphate (ATP) and a reduced unit of NADP+, called (NADP plus an ...
The role of NADPH in oxygen-producing photosynthesis is to ____. a) supply hydrogen to the carbohydrate; b) supply carbon to the carbohydrate; c) supply energy that can be used to form a carbohydrate; d) transfer oxygens from the third ...
The power of the yeast genetic system was used to test the hypothesis that inactivating TPI blocks glycolysis and results in generation of from the pentose phosphate pathway.
Using that energy they strip off electrons and put them onto a high energy electron carrier called NADPH they also use the energy of those electrons to make a molecule called ADP an energy molecule that's going to be needed later on in the Calvin ...
If the light intensity is not a limiting factor, there will usually be a shortage of NADP+ as accumulates within the stroma (see light independent reaction).
It appeared from noncyclic phtotphosphorylation that PS1 was responsible for NADPH production, while in cyclic photophosphorylation it is important for ATP production.
The energy of the sun is captured by pigments found in photosynthetic organisms and the energy is captured in such a way as to produce ATP and reducing power in the form of electrons which are carried by the coenzyme, (formed from the vitamin ...
However, if there is plenty of NADPH, something different happens.
The electron from PS I is passed to the electron carriers used in PS II. ATP is formed and the electrons return to PS I to fill the space.
dark reaction - in photosynthesis, the ATP and are used to drive a series of Acarbon-fixation@ reactions in which CO2 from the air is used to form sugar molecules.
The carbon-fixing reactions of the second stage of photosynthesis; energy stored in ATP and NADPH by the light-dependent reactions is used to reduce carbon from carbon dioxide to simple sugars; light is not required for these reactions.
transport 1) A series of coupled oxidation/reduction reactions where electrons are passed like hot potatoes from one membrane-bound protein/enzyme to another before being finally attached to a terminal electron acceptor (usually oxygen or ).
light reaction that part of the photosynthetic process that, in the presence of light, captures energy to form ATP and NADPH2 to be used to synthesize complex organic molecules in the dark reaction
lignification Impregnated with lignin.
