Chloroplast cell.
These reactions are also called the light-independent reactions because they are not directly driven by light. In the Calvin cycle, carbon atoms from CO 2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.
Martin Jonikas. Chloroplasts are a specialized structure found inside the cells of land plants and red and green algae. Through the process of photosynthesis, chloroplasts convert sunlight and atmospheric carbon dioxide into the starches we eat and the oxygen we breathe. Despite their importance, we have only a fuzzy idea of how chloroplasts work.Aug 2, 2014 · Chloroplasts are tiny factories inside the cells of plants. They are also found in the cells of other organisms that use photosynthesis. Chloroplasts take the energy from the sunlight and use it to make plant food. The food can be used immediately to give cells energy or it can be stored as sugar or starch. Mitochondria and Chloroplasts Mitochondria. Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule.The formation of ATP from the breakdown of glucose is known as cellular respiration.A chloroplast is a type of structure, called an organelle, that is found in plants and is where photosynthesis occurs.
