Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II. Photosystem I and photosystem II both contain chlorophyll as molecules.
The initial reactions in photosynthesis are known as the light-dependent reactions. These reactions occur in the thylakoid membranes of the chloroplast and involve the absorption of light energy to drive the conversion of water into oxygen, ATP, and NADPH.
Yes, light is common to both cellular respiration and the light reactions of photosynthesis. In photosynthesis, light energy is used to convert water and carbon dioxide into glucose and oxygen. In cellular respiration, the energy stored in glucose is released through a series of reactions to produce ATP, and light is not directly involved in this process.
The light-dependent reactions in photosynthesis generate oxygen from water. No ATP is produced during this step.
In the light reactions of photosynthesis, oxygen is released as a byproduct. Oxygen is not directly involved in the dark reactions (Calvin cycle), which utilize ATP and NADPH produced during the light reactions to convert carbon dioxide into sugars.
The hydrogen atoms in the water molecule are used during photosynthesis. Water molecules are split into oxygen, protons, and electrons during the light-dependent reactions in photosynthesis.
donating electrons to photosystem II
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.
The oxygen produced during photosynthesis comes directly from water. In the light-dependent reactions of photosynthesis, water molecules are split to release oxygen as a byproduct. This process is known as photolysis.
