Mar 20, 2024 · The process. During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
The first phase of photosynthesis is the light-dependent reactions. This phase requires sunlight. Chlorophyll absorbs energy from sunlight and converts it into chemical energy. This chemical energy is stored in two forms: The light-dependent reactions occur on the thylakoid membrane within the chloroplast.
Photosynthesis takes place in two sequential stages: the light-dependent reactions and the light-independent reactions (Figure 8.19). In the light-dependent reaction s , energy from sunlight is absorbed by pigment molecules in photosynthetic membranes and converted into stored chemical energy.
Figure 8.7 Photosynthesis takes place in two stages: light dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make G3P from CO 2.
Jan 29, 2024 · Functions of Chloroplasts. The primary function of chloroplasts is photosynthesis, comprising two stages: the light-dependent reactions occurring in the thylakoids, and the light-independent Calvin Cycle happening in the stroma. They also play roles in fatty acid synthesis, amino acid synthesis, and the immune response.
May 25, 2017 · The light-dependent reactions take place in the thylakoid membrane, inside chloroplasts. Since they are light 'dependent' reactions, you can guess that these reactions need light to work. Remember that the purpose of this first part of photosynthesis is to convert sunlight energy into other forms of energy?
Photosynthesis takes place inside chloroplasts which are small objects inside plant cells. Chloroplasts contain a green substance called chlorophyll. This traps the light energy needed to make ...
