The energy to remove hydrogen from NADPH comes from chemical reactions that are part of metabolic pathways, such as cellular respiration or photosynthesis. In these processes, NADPH is oxidized to NADP+, releasing electrons and protons, which are then used in various biochemical reactions. The energy released during the oxidation of NADPH is harnessed to drive reactions that require energy input, such as the synthesis of ATP or the reduction of other molecules.

What high energy electron carrier is needed to transform 2 electrons and one hydrogen ion into NADPH?
The high-energy electron carrier needed to transform 2 electrons and one hydrogen ion into NADPH is NADP+ (nicotinamide adenine dinucleotide phosphate). During this process, NADP+ accepts the electrons and hydrogen ion, becoming reduced to NADPH. This reaction is essential in photosynthesis and various metabolic pathways where NADPH serves as a reducing agent.
What two products of the light dependent reactions provides energy for the independent light reactions?
ATP and NADPH
Where does the ATP and NADPH in the Calvin cycle come from?
ATP is produced through the process of cellular respiration in the mitochondria of plant cells. NADPH is generated during the light reactions of photosynthesis in the chloroplasts. Both ATP and NADPH are used as energy sources for the Calvin cycle to run the biochemical reactions that convert carbon dioxide into glucose.
Atp and nadph molecules generated during the light reactions power the dark reactions?
During the light reactions of photosynthesis, ATP and NADPH molecules are produced. These high-energy molecules are then used in the Calvin cycle (dark reactions) to convert carbon dioxide into glucose. ATP provides energy while NADPH provides reducing power for these reactions.
What does NADPH provide in the Calvin benson cycle?
NADPH provides reducing power in the Calvin cycle, enabling the conversion of carbon dioxide into sugars. It is essential for the reduction of 3-phosphoglycerate to glyceraldehyde-3-phosphate, which is a key step in the cycle for the production of carbohydrates.
What the functions of NADPH?
An easily understood explanation is: NADPH carries high-energy electrons that were produced by light absorption in chlorophyll to chemical reactions elsewhere in the cell. NADPH is a chemical compound which gives hydrogen atom for the formation of the carbohydrate in the dark reactions of the photosynthesis. Photosynthesis is completed in two steps: Light reactions dark reactions Another explanation: NADPH provides a source of hydrogen for reduction reactions in photosynthesis. In the light independent reactions carbon dioxide is converted into carbohydrate: CO2 --------> CH2O NADPH provides the hydrogen needed for this reaction.

Electron carrier that provides the high energy electrons needed to make carbon-hydrogen bonds in the third stage of photosynthesis?
NADPH (nicotinamide adenine dinucleotide phosphate) is the electron carrier that provides the high-energy electrons required to make carbon-hydrogen bonds in the third stage of photosynthesis (Calvin cycle). These electrons are essential for reducing carbon dioxide to produce sugars and other organic compounds. NADPH is produced during the light-dependent reactions of photosynthesis.
What molecule leaves the thylakoid to provide hydrogen for the carbon-fixation reaction?
The molecule that leaves the thylakoid to provide hydrogen for the carbon-fixation reaction is NADPH. NADPH is produced during the light-dependent reactions of photosynthesis and is used in the Calvin cycle, where it provides the necessary reducing power to convert carbon dioxide into glucose.
What two products of the light dependent reactions provides energy for the independent light reactions?
ATP and NADPH
What compound provides the reducing power for Calvin cycle reactions?
NADPH
Which process during photosynthesis involves addition of hydrogen?
The process during photosynthesis that involves the addition of hydrogen is the reduction of NADP+ to NADPH. This occurs during the light-dependent reactions, where light energy is used to drive the conversion of NADP+ into NADPH by adding hydrogen ions and electrons from water.
Where does the ATP and NADPH in the Calvin cycle come from?
ATP is produced through the process of cellular respiration in the mitochondria of plant cells. NADPH is generated during the light reactions of photosynthesis in the chloroplasts. Both ATP and NADPH are used as energy sources for the Calvin cycle to run the biochemical reactions that convert carbon dioxide into glucose.
Is a NADPH equivalent to an APT?
No, NADPH (nicotinamide adenine dinucleotide phosphate) is a molecule involved in energy metabolism and reducing reactions, while ATP (adenosine triphosphate) is the primary source of energy for cellular processes. They serve different functions in the cell.
NADPH is formed when the electrons acceptor NAPD combines with what?
NADPH is formed when the electron acceptor NADP+ combines with electrons and a hydrogen ion (H+). This reduction reaction takes place during the light reactions of photosynthesis, where energy from sunlight is used to drive the electron transport chain and ultimately produce NADPH.
