The light (dependent) reactions.
Water is split into its components, hydrogen and oxygen. Gaseous oxygen is released as a by-product, the hydrogens are further split into protons and electrons, the electrons are use to replenish those lost by Photosystem II, and the protons are eventually picked up by NADP coenzyme. The coenzyme is reduced to NADPH, which is later utilized in the dark reactions to reduce atmospheric carbon dioxide.

Which organ uses water in photosynthesis?
The chloroplasts in plant cells are the organelles that use water for photosynthesis. Water molecules are split into oxygen, electrons, and protons during photosynthesis, providing the necessary electrons for the light-dependent reactions to occur.
Which of the reactants in photosynthesis produces oxygen during the reactions of photosynthesis?
That would be the water. Light form the sun is used to split water into hydrogen and oxygen. Oxygen, as we know, is released as a waste product that we use. Hydrogen is then carried to another series of reactions to create energy for the plant.
What reactions use sunlight?
Photosynthesis is a reaction that uses sunlight to convert carbon dioxide and water into glucose and oxygen in plants. In humans, sunlight activates the synthesis of vitamin D in the skin.
Which set of reactions uses H2O and produces O2?
The process of photosynthesis uses H2O and produces O2. During photosynthesis, plants and other organisms with chlorophyll absorb sunlight and use it to convert water and carbon dioxide into oxygen and glucose.
During the dark reactions the reaction center splits water?
During the dark reactions (Calvin cycle) of photosynthesis, water is not split. Instead, the dark reactions use the products of the light reactions (ATP and NADPH) to convert carbon dioxide into glucose through a series of enzyme-controlled reactions. The splitting of water occurs in the light reactions at Photosystem II to generate oxygen, electrons, and protons.
One of the two parts of photosynthesis?
One of the two parts of photosynthesis is the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts. These reactions use light energy to split water molecules and produce ATP and NADPH.
What are the 2 main reactions in photosynthesis?
Photosynthesis happens in two stages, also called reactions. The first stage is the light-dependent stage. In this stage light energy is absorbed by chlorophyll and converted into chemical energy, and water is split to produce hydrogen. The unwanted oxygen from the water is released. The second stage is the light-independent stage. In this stage the chemical energy and the hydrogen from the first stage are used to convert carbon dioxide into carbohydrates, such as glucose.

What do the light reactions of photosynthesis use?
The light reactions of photosynthesis use light energy to convert water and sunlight into ATP and NADPH, which are energy-rich molecules needed for the Calvin cycle to produce glucose. These reactions take place in the thylakoid membranes of the chloroplast.
Carbohydrate-synthesizing reactions of photosynthesis directly require?
The carbohydrate-synthesizing reactions of photosynthesis directly require carbon dioxide, water, and sunlight. Through the process of photosynthesis, plants use these raw materials to produce glucose, a simple sugar that serves as the building block for larger carbohydrates such as starch.
What reactions use sunlight?
Photosynthesis is a reaction that uses sunlight to convert carbon dioxide and water into glucose and oxygen in plants. In humans, sunlight activates the synthesis of vitamin D in the skin.
Which set of reactions uses H2O and produces O2?
The process of photosynthesis uses H2O and produces O2. During photosynthesis, plants and other organisms with chlorophyll absorb sunlight and use it to convert water and carbon dioxide into oxygen and glucose.
How do phytoplankton utilize photosynthesis for their energy production?
Phytoplankton use photosynthesis to convert sunlight, carbon dioxide, and water into energy in the form of glucose. They have chlorophyll pigments that capture sunlight and use it to drive the chemical reactions that produce energy for the organism.
What is the by product made in photosynthesis?
The byproducts of photosynthesis are oxygen and glucose. These are made when the processes known as the Kalvin Cycle and the Krebs Cycle.
A compound that is split during photosynthesis is?
Water is the compound that is split during photosynthesis, producing oxygen and hydrogen ions in the process. This splitting of water is a crucial step in the light-dependent reactions of photosynthesis that ultimately leads to the production of ATP and NADPH for use in the Calvin cycle.
