Where do the hydrogen ions comes from for the photosystems of the light-dependent reactions?
splitting of water molecules
What else can I help you with?
What is the evidence that there are two photosystems in plants?
The evidence for two photosystems in plants comes from experiments using isolated chloroplasts, which have shown that two distinct light reactions occur in the thylakoid membrane. Additionally, differences in absorption spectra and electron transport pathways of Photosystem I and Photosystem II provide further evidence for the existence of two separate photosystems.
Where does the heat of the sun come from?
The heat of the sun comes from nuclear fusion reactions in its core. These reactions convert hydrogen into helium, releasing enormous amounts of energy in the form of heat and light.
How do photosystem 1 and 2 allow the calvin cycle to work?
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
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.
What types of reactions occur in a star?
In a star, nuclear fusion reactions occur. These reactions involve the conversion of hydrogen into helium, releasing immense amounts of energy in the process. This energy is what powers the star and allows it to shine.
What are true reactions of the Sun?
They are fusion reactions, and The force to get the reactions to occur comes from gravity.
Most of the light emitted by the sun comes from where?
Most of the light emitted by the Sun comes from its core, where nuclear fusion reactions occur. These reactions convert hydrogen into helium, releasing a tremendous amount of energy in the form of light and heat. This energy then travels outwards, eventually reaching the Sun's surface and being emitted into space as sunlight.
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.
What is source of the sun's energy?
The Sun's energy comes from nuclear fusion reactions happening in its core. These reactions convert hydrogen into helium, releasing vast amounts of energy in the form of light and heat. This process has been ongoing for billions of years, providing Earth with the energy it needs for life.
Where did the energy come from that powers the sun?
The energy that powers the sun comes from nuclear fusion reactions happening in its core, where hydrogen atoms combine to form helium, releasing a large amount of energy in the process.
What heats the sun?
The heat generated in the sun comes from nuclear fusion reactions in its core, where hydrogen atoms are combined to form helium. This process releases a massive amount of energy in the form of heat and light.
IS hydrogen necessary in the electron transport chain comes from the splitting of carbon dioxide molecules?
Hydrogen is essential in the electron transport chain, but it does not come from the splitting of carbon dioxide molecules. Instead, hydrogen is derived from the splitting of water molecules during the light reactions of photosynthesis. This hydrogen is then used to generate a proton gradient that drives ATP synthesis in the electron transport chain.
