Photosynthesis is defined as the process by which green plants manufacture their food (organic compounds) making use of carbon dioxide and water in the presence of sunlight. It is also the synthesis of carbohydrate from sunlight, water and CO2 by the green plants. It is an endergonic and anabolic process. Bacteria show an oxygenic photosynthesis as they do not use water and do not evolve oxygen. Cyanobacteria (blue green algae) evolved oxygen first time in evolution as they show oxygenic photosynthesis

Develop 3D printable natural and synthetic polymer systems, for biological scaffolds, that are tough enough to produce highly complex parts with small internal features and porosity to allow for microvascular regrowth to attach onto the scaffolds. To obtain a scaffold with suitable mechanical and viscoelastic properties (Young’s modulus 0.35± .11 MPa, Tensile stiffness 8.59±3.5 MPa, Equil. Modulus 13.6±1.5 MPa), it is very important to choose the proper polymeric material and fabrication technique10

Abstract The undersides of three pieces of spinach leaves were painted with clear nail polish. Clear tape was placed onto the area and carefully removed to get the leaf impression. The impression was viewed under the microscope and the amount of stomata was recorded in the data table. Introduction Photosynthesis is the conversion of unusable light energy to usable chemical energy inside chlorophyll. This energy is stored in sugar. The chemical equation for photosynthesis is 6CO2 + 6H2O ------>

pigments interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs, which make their own food through the process of photosynthesis. (Unknown author,1997). Chlorophylls (refer to appendix) contain a porphyrin ring. This is a stable ring-shaped molecule and electrons are free to migrate.”

as natural gas. Petroleum hydrocarbons could be divided into four classes: saturates (pentane, hexadecane, octacosane, cyclohexane), aromatics (naphthalene, phenanthrene, benzene, pyrene), asphaltenes (phenols, fatty acids, ketones, esters, and porphyrins), and resins (pyridines, quinolines, carbazoles, sulfoxides and amides)”. : P 78-79 Natural gas is the world 's third major energy source, estimated at 21% of total prime energy usage (www.indexmundi.com/commodities/market). On the other hand, environmental

belong in the place it is in, something unusual and that was exactly what this girl was. The “thing” being unusual or out of place in the story, is the narrator, a girl who we are not aware name-wise but has a disease called “Porphyria.” “The term ‘porphyrin comes from the

Hemoglobin Bassett – Consequences in Structure, Function, Stability, and Clinical Effects of a Hemoglobin α94 Aspartic Acid to Alanine Mutation Introduction: Carrying carbon dioxide from the tissues to the lungs and oxygen from the lungs to the tissues, hemoglobin is the protein involved in the transport of oxygen in the human body (1). Most hemoglobin in humans exists as the tetramer denoted as α2β2, also known as Hemoglobin A or HbA. It consists of 2 pairs dimers, α1β1 and α2β2, which are linked

Background My career in energy technology began in 2012, when I started my master’s coursework and research in electrochemistry at the University of Louisville’s Department of Chemistry. Since then, I have developed an extensive skillset, focusing mainly on the development and usage of semiconductor materials such as titanium oxide (TiO2), tin-oxide (SnO2), birnessite-manganese oxide (b-MnO2), and neodymium oxide (Nd2O3). I have extensively studied the photophysics and photochemistry of energetic

All proteins are composed of amino acids, organic molecules made from Carbon, Hydrogen, Oxygen and Nitrogen. Collagen is the most ample protein in mammals, in fact collagen constitutes around 25 % of a mammals entire protein content, Collagen is more precisely a family of proteins rather than one particular protein. Fibroblasts are the cells that usually produce collagen. Collagen is a complex molecules so doesn’t have a simple chemical structure for it; diagrams usually show collagen as a fiber

An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase, during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic
