As we studied in Cellular Respiration, aerobic cellular respiration taps into the oxidizing ability of oxygen to synthesize the organic compounds that are used to power cellular processes. Biology, while super informative and exciting to science junkies, can be a little dry. Test. Photosynthesis is defined as the process, used by green plants and photosynthetic bacteria, where electromagnetic radiation is converted to chemical energy and uses the energy of light to convert carbon dioxide and water to carbohydrates and oxygen. photosynthesis process by which plants and some other organisms use light energy to power chemical reactions that convert water and carbon dioxide into oxygen and high-energy carboydrates such as sugars and starches Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. In the first step, energy from light is stored in the bonds of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate . To do this, the chloroplasts will combine units of carbon dioxide into chains of 6 carbons, 12 hydrogens, and 6 oxygens. Plants, unlike animals, can make their own food. This is glucose, which can then be modified and combined with other glucose molecules to be stored as starches and complex sugars like fructose. photosynthesis. organism that can capture energy from sunlight or chemicals an…. ADP - ADP stands for adenosine diphosphate, a product of the Calvin cycle that is used in the light-dependent reactions. they dye or pigment under test) and the distance moved by the solvent (known as the solvent front) along the paper, where both distances are measured from the common origin baseline. plants, cyanobacteria) In photosynthesis, the inorganic compounds of carbon dioxide, water, and sunlight are used by photoautotrophs to produce glucose, oxygen, and water. Our mission is to provide a free, world-class education to anyone, anywhere. After the process is complete, it releases oxygen and produces glyceraldehyde-3-phosphate (GA3P), simple carbohydrate molecules (which are high in energy) that can subsequently be converted into glucose, sucrose, or any of dozens of other sugar molecules. Spelling Bee Test your spelling acumen. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis Definition. Biology is brought to you with support from the Amgen Foundation. 6CO₂ + 12H₂O --> C₆H₁₂O₆ + 6O₂ + 6H₂O. Definition of Photosynthesis. Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves. Match. Carbon dioxide, water and light are all needed for photosynthesis to take place. The wavelengths of light that are absorbed most are the ones which stimulate photosynthesis the most.
