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.
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 happens to water during the process of photosynthesis?
During photosynthesis, water molecules are split into oxygen and hydrogen ions. The oxygen is released into the atmosphere, while the hydrogen ions are used to create energy-rich molecules like ATP and NADPH that are essential for the plant's growth and survival.
What are the requirements for photosynthesis and briefly describe how each is involved in the light and dark reaction?
photosynthesis /pho·to·syn·the·sis/ (fo?to-sin´thi-sis) a chemical combination caused by the action of light; specifically, the formation of carbohydrates from carbon dioxoide and water in the chlorophyll tissue of plants under the influence of light.photosynthet´ic
How does water contribute to the process of photosynthesis?
Water plays a crucial role in photosynthesis by providing the necessary hydrogen atoms for the production of glucose. During photosynthesis, water molecules are split into oxygen and hydrogen ions. The hydrogen ions are then used to help convert carbon dioxide into glucose, which is the main source of energy for plants.

Where does the water go from photosynthesis?
The water used in photosynthesis is split into oxygen and hydrogen ions. The oxygen is released into the atmosphere, while the hydrogen ions are used to produce energy in the form of ATP and NADPH that the plant can use to make glucose.

What are the three product from the splitting of the water?
The three products from the splitting of water are oxygen gas (O2), hydrogen ions (H+), and electrons (e-). This process is a key step in photosynthesis, where sunlight is used to convert water into oxygen and energy-rich molecules like 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.

In photosynthesis the source of electrons is?
The electrons come from water. In the light dependent stage water is split into hydrogen ions (H+), electrons and oxygen. The electrons are passed on to chlorophyll, the H+ ions combine with NADP to form NADPH and the oxygen is released.
Function 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.
What provides the energy to remove the Hydrogen from NADPH?
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.
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.
