Additionally, pigments in zooxanthellae (MAAs, or mycosporine-like amino acids) protect zooxanthellae against ultraviolet radiation do so only up to about 340 nm. If the energy of UV-A light between 340 nm and 380 nm is absorbed by photopigments, but not used in photosynthesis, how else would it be dissipated? See Table 11.
The net process of photosynthesis is described by the following equation: 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunlight to form sugars, oxygen is released as a by-product of this reaction....
Describe the second portion of photosynthesis?
Results of testing show there are clear differences in the rate of photosynthesis when light sources of different hue (or color) are used. See Figure 25.
The algae and plants, trap energy from sunlight with chlorophyll.
Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light. They also have a red pigment called phycoerythrin that absorbs green light and extends the range of photosynthesis. The red pigment is found in vegetables. Some red algae are in fact nearly black, so that increases their photosynthetic efficiency. Brown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range. These red and brown algae grow to depths around 270 meters where the light is less than 1% of surface light.
We now shift our attention to photosynthesis, the second main ..
Purdue University physicists are part of an international group using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun’s energy into carbohydrates used to power cellular processes.

Water (H2O) is split in this process, releasing oxygen (O2) and hydrogen ions (H+). The electrons from the electron transport chain combine with these H+ ions and nicotinamide adenine dinucleotide phosphate ions (NADP+) to form adenosine triphosphate (ATP) and a reduced unit of NADP+, called NADPH (NADP plus an electron, or H). These energy storage forms, ATP and NADPH, are used to convert carbon dioxide (CO2) to build carbohydrates during the second phase of photosynthesis. Plants can then break down these carbohydrates to fuel their existence.
Overview of Photosynthesis | Boundless Biology
To a plant, sunbathing is life. Literally. In fact, plants have evolved all sorts of ways to maximize their exposure to the sun while at the same time preventing loss of critically needed water. Plants, as well as some algae and bacteria, perform photosynthesis, a process that involves the capture and use of the Sun’s energy to create biological compounds. Photosynthetic organisms generate these compounds using carbon dioxide (CO2) and water (H2O), and the products they release are oxygen (O2) and carbohydrates as byproducts.
