What is the role of NADPH in photosynthesis quizlet?
What is the role of NADPH in photosynthesis? NADPH is an electron carrier that accepts a pair of high-energy electrons and transfers them, along with most of their energy, to another molecule. NADPH plays a big role in the light-independent reaction when it is used, along with ATP, to produce high energy sugars.
What is the function of the NADPH molecule?
Function. NADPH provides the reducing equivalents, usually hydrogen atoms, for biosynthetic reactions and the oxidation-reduction involved in protecting against the toxicity of reactive oxygen species (ROS), allowing the regeneration of glutathione (GSH).
What is the role of NADH and NADPH in photosynthesis?
NADH is produced in glycolysis and Krebs cycle and is used in the electron transport chain to produce ATP via oxidative phosphorylation. NADPH is produced in the light reaction of photosynthesis and is used in the Calvin cycle to assimilate carbon dioxide.
What is the function of NADPH quizlet?
The function of NADPH is to carry high-energy electrons, produced through light absorption from chlorophyll, to chemical reactions in other parts of the cell.
What are the roles of NADPH and ATP in photosynthesis?
So in summary, there are two main roles of NADPH and ATP: (1) they tie the light dependent reactions and the light independent reactions together and (2) they act as sources of energy to take the energy from the sun to the light independent reactions to make the plants food.
What is NADH in photosynthesis?
NADH – An analog of NADPH lacking a phosphate group, which functions in catabolic reactions. Electron Carrier – Molecules uses as intermediates in the transfer of electrons in biological pathways.
What is the function of NADPH and ATP in photosynthesis?
The electrons and protons are used to produce NADPH (the reduced form of nicotine adenine dinucleotide phosphoric acid) and ATP (adenosine triphosphate). ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis.
What is the role of NADPH in the Calvin cycle?
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar.
What is the role of NADPH in the Calvin cycle quizlet?
In the Calvin cycle, the ATP made in the light reaction provides the energy and the NADPH provides the reducing power needed to make sugar from carbon dioxide and water.
What is the role of NADPH in Calvin cycle?
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar.
What are the roles of ATP and NADPH in photosynthesis quizlet?
What are the roles of ATP and NADPH in photosynthesis? Both of these molecules carry energy; in the case of NADPH, it has reducing power that is used to fuel the process of making carbohydrate molecules in light-independent reactions.
What happens to NADPH in photosynthesis?
Photosynthesis uses a different energy carrier, NADPH, but it functions in a comparable way. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.
What is the role of ATP and NADPH in photosynthesis?
So in summary, there are two main roles of NADPH and ATP: (1) they tie the light dependent reactions and the light independent reactions together and (2) they act as sources of energy to take the energy from the sun to the light independent reactions to make the plants food.
Where is NADPH used?
NADPH is used in the biosynthesis (production) of lipids (fatty acids and cholesterols), neurotransmitters, nucleotides and amino acids. It also plays a major role in plant photosynthesis as an electron acceptor in the light reaction and donor in the light-independent reactions.
What are NADPH and ATP used for in photosynthesis?
NADPH formation. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
