How Is Light Used in Photosynthesis?. Photosynthesis is when energy from light, either from the sun or an artificial source, is used to produce sugar within a cell. During photosynthesis, water and carbon enter the cells and are converted into sugar and oxygen, and then released.
The Process of Photosynthesis
Photosynthesis is when energy from light, either from the sun or an artificial source, is used to produce sugar within a cell. During photosynthesis, water and carbon enter the cells and are converted into sugar and oxygen, and then released.
Light
Light is an essential element for photosynthesis. Light energy is gathered by the chlorophyll in the chloroplasts during the light dependent process. The cells make energy carrier molecules to be used in the second process, the light independent process. Plants also use the light energy from the light dependent phase and convert it into C-C covalent bonds of carbohydrates during the light independent process, also called dark reactions.
Release of Light Energy
Light energy cannot be directly used by living organisms, but they can convert it to C-C bond energy. This can be released by glycosis and other metabolic processes. Not all wavelengths of light can support the process of photosynthesis.
Photosynthesis
Three factors have an effect on photosynthesis: 1) light radiance and wavelength, 2) carbon dioxide concentration, and 3) temperature. Water is split during the process of photosynthesis to release oxygen. Sugar is the major product of photosynthesis, and oxygen is the primary waste product.
