The two parts of the biochemical pathway of photosynthesis are the energy-fixing reaction and the carbon-fixing reaction. The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Chlorophyll absorbs a photon of light, becomes excited and donates an activated electron to the reaction center. The electron used in this process continues along the ETC to eventually aid in the production of NADPH. For example, chloroplasts in green algae are very different from chloroplasts in vascular plants. Photons can be used to remove carbon dioxide (CO2) and other organic compounds. That particular light wavelength is reflected from the plant, so it appears green. This cookie is set by GDPR Cookie Consent plugin. Q. an organelle found in plant and algae cells where photosynthesis occurs. Plants, on the other hand, are experts at capturing light energy and using it to make sugars through a process called photosynthesis. Photosynthetic organisms capture energy from sunlight with pigments. NADPH plays a big role in the light-independent reaction when it is used, along with ATP, to produce high energy sugars. Water enters the plants by the roots, and travels to the leaves in the xylem. There are six distinct types of chlorophyll, but the main types are chlorophyll A and chlorophyll B. Chlorophyll A transfers energy to the reaction center and donates two excited electrons to the electron transport chain. Chlorophyll is a pigment that plays an important role in photosynthesis. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution.
