      • This stage is so-called because it depends on light being available. The reactions of this stage also require specific enzymes to catalyse them. Light energy absorbed by chlorophyll is converted into chemical energy. Some of this energy is used to split water into hydrogen and oxygen.

  2. photosynthesis keeps the levels of oxygen and carbon dioxide in the atmosphere in balance – without it we would very quickly run out of oxygen. Photosynthesis is really important for the plant...

  4. Oct 4, 2023 · Photosynthesis occurs in two, closely-linked stages: the light-dependent stage, which takes place in the thylakoids, and the light-independent stage, which takes place in the stroma.

  5. Figure 8.3.1 8.3. 1: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

  6. The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H 2 O) is oxidized, and oxygen (O 2 ) is released.

  7. Jul 30, 2017 · Photosynthesis is the biochemical pathway which converts the energy of light into the bonds of glucose molecules. The process of photosynthesis occurs in two steps. In the first step, energy from light is stored in the bonds of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH).

  8. Sep 21, 2021 · Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
