A Cell Free Artificial Platform For Harvesting Light Energy

New revolutionary technologies are emerging fast to address this issue of increased electrical power generation and storage needs. An example is teams of MIT scientists that have created a synthetic, self-assembling chloroplast that can be break and reassemble repeatedly, a self-restoring solar cell. (Dillow, 2010). Another example is a company called Bloom Energy, which is producing tiny fuel cell boxes called “Bloom Boxes.” Two of these can power an average U.S. home. Each device is about the size of a standard brick. Although they need to be surrounded by a larger unit that takes in an energy source, they are still about the size of a refrigerator. This alternative is already being tested by companies such as Google and eBay (Siegler, 2010).

Photosynthesis uses the energy of sunlight to convert water and carbon dioxide into high-energy sugars and oxygen.

Percival Zhang and Zhiguang Zhu, researchers at Virginia Tech, in Blacksburg, designed an incipient biobattery with a more preponderant output per weight than the typical lithium-ion batteries utilized in most electronics. They described the research online last month in the journal Nature

Photosynthesis is the chemical process of capturing light energy and converting it into a chemical form. Through a series of reactions, the process takes sunlight, carbon dioxide, and water to produce oxygen and a carbohydrate, usually a sugar called glucose. The oxygen is released into the atmosphere, while the glucose is stored inside the plant. Because sunlight is required, photosynthesis is a diurnal activity.

Photosynthesis Introduction: Photosynthesis is a process by which light energy is converted into chemical energy. Understanding energy conversions is not trivial, and this bio-coach activity is designed to enhance our understanding and retention of the content by illustrating and animating the fundamental processes involved in photosynthesis. An Overview of Photosynthesis: Photosynthesis converts light energy into the chemical energy of sugars and other organic compounds. This process consists of a series of chemical reactions that require carbon dioxide (CO2) and water (H2O) and store chemical energy in the form of sugar.

The site for photosynthesis is chloroplast that captures light by pigment molecules called chlorophylls. High-energy electrons with great reducing potential are produced in this process. These electrons are used to produce NADPH

Introduction: Plants are able to utilize a broad spectrum of light that can be used by chlorophyll within them to do something biologically useful. Moreover, they use the energy from light to manufacturer the foundation molecules for the food that we eat and as well the O2 we breathe. (2) It is deeply imperative to gain an understanding about how light is used to produce energy for themselves and for us.

First, a photon of light hits a pigment molecule in a light-harvesting complex--located in the Thylakoid membrane--boosting one of its electrons to a higher energy level. Then as the electron falls back to its ground state, another electron in a nearby pigment molecule gets excited. This process happens over and over again, from pigment molecule to pigment molecule, until it reaches the pair of chlorophyll a molecules in the Photosystem II reaction-center complex. Then it excites an in this pair of chlorophylls to a higher energy state. Next, this electron is transferred from the excited chlorophyll pair to the primary electron acceptor. When this happens the chlorophyll pair becomes positively charged (due to the missing electron), and an

All organisms on earth depend on photosynthesis, in which light energy is used to make sugar and other food molecules from carbon dioxide and water. For example, plants and other photo-synthesizers need only energy from sunlight, carbon dioxide from air, and water from the soil to make the sugar glucose. Photosynthesis is the most important chemical process on earth because it provides food for virtually all organisms, not only for photo-synthesizers but for the organisms that eat them. Plants can capture the energy of the sun by a chemical process called photosynthesis. This chemical reaction can be described by the following simple equation:

We chose renewable energy, and solar energy for specific with our simple and naive thought of its potential in future and global scale influence. Having no contact with any professional in the field researching at Vietnam, we started like every teenager, with Google and Wikipedia. I wanted to do a research because I was bored with the traditional class. As I anticipated, the experience contradictory to the class. Start reading about solar cell was like entering a forest I’d never been in before. Books and scientific papers about it were the trees and soil, they all looked the same to a newcomer like me. At first, I felt lost and frustrated. But after getting used to it, I wandered. Sometimes, I picked up a rock, played with it, tried to throw it. I knelt down and examine the soil. I climbed the trees and learned the differences between them. I read and learned not because I needed to prepare for a test or exam as I did for the last eleven years before. I learned because I wanted to make something of my own, to try new thing and see how it turned out. Finally, when the forest felt like home, I started producing ideas. There were bad ideas, which can be theoretically eliminated. Some ideas I thought good, but later found out somebody had done it. And then came the idea I proud the most. I borrowed a material, Phycobiliprotein, and the mechanism from the master of using light energy, nature, to

Photosynthesis is a process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy.

Photosynthesis is a fundamental process that utilises light to produce energy. The energy is initially captured in the form of ATP and NADH in the Light Reaction. The Calvin Cycle then uses stored energy from ATP and NADH to produce energy in the form of sugar to store or to use. Water is split during the Light Reaction into its elemental forms, and oxygen and hydrogen are released as by products (Renger and Renger, 2008). To use free energy to bind oxygen to hydrogen to make water, the thylakoid membrane produces ATP using the electron transport chain. Photosynthesis produces oxygen and respiration uses oxygen. (Blankenship, 1992)

Bioluminescence is a “cold light”, meaning that the light source does not waste energy producing heat, making it highly effective. Further studies and exploration have allowed for major scientific advancements to take place. For instance, by splicing together firefly and marine bacteria genes into trees, bioluminescent trees called tree lights can be created. The tree leaves photosynthesize during the day, then reuse that energy at night. The leaves could be turned on and off by utilizing the tree’s circadian rhythm, which is when

Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth.

Photosynthesis is a process in plants, algae, and some prokaryotes, that coverts solar insulation into chemical energy stored in glucose or other organic compounds. Photosynthesis occurs in slightly different ways in higher plants relative to photosynthetic bacteria. Photosynthesis is an important process because it harnesses the sun's energy into utilizable forms of energy on earth. Most biological organisms such as animals and fungi are unable to directly use light energy to power biological processes such as active transport, cell division and muscle movement. ATP is used to power these processes. Photosynthesis converts light energy into chemical energy in the form of glucose and then the process of cellular respiration converts energy in glucose to energy in the form of ATP which is ultimately used to power biological processes. The energy produced by photosynthesis forms the foundation of virtually all terrestrial and aquatic food chains. As a result, photosynthesis is the crucial source of carbon in the organic molecules found in most organisms. The high oxygen concentration in the atmosphere is derived directly from the light reactions of photosynthesis. Prior to the evolution of photosynthesis on earth, the atmosphere was absent of any oxygen
