This discovery also showed that photosynthetic reactions are different than others because they give up oxygen‚ whereas others use CO2. Lastly‚ it showed that oxidation-reduction reactions are a major part of photosynthesis. Electron-acceptor molecules are being reduced and oxidized as electrons move around during photosynthesis. As part of this movement‚ electrons reduce NADP+ to NADPH‚ which is used in light-independent reactions. A dye‚ DPIP‚ is needed to distinguish this process‚ where the

The two factors that we will be testing in this experiments are: Lactase Enzyme and Lactose. Lactase is a protein located in the human small intestine‚ while lactose is a term to define the sugar found in milk. Milk is a substance that contains nutrients necessary for our bodies‚ however‚ some people are unable to consume lactose related products‚ and so they are medically classified as Lactose Intolerants. The purpose of this experiment is to examine and illustrate the way that lactose gets affected

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach

CO2 into simple sugars. The process follows the equation: 6CO2+H2O+Light C6H12O6+6CO2. CO2 is converted into simple sugars in the Calvin cycle‚ which occurs in three stages. It takes 6 “turns” of the Calvin cycle for the organism to produce one molecule of glucose. Organisms that are autotrophs use photosynthesis to make their own energy to survive. Heterotrophs eat other organisms because they cannot synthesize their own energy‚ therefor photosynthesis is an important building block of life. (Raven

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

100ml of 0.4M CuSO4 is prepared for the experiment but during the practical the water level was increase than the 100ml mark in volumetric flask. So‚ it makes error in the concentration of CuSO4 primary solution. CuSO4 has ability to absorb water molecules from environment therefore when calculating the mass of CuSO4 it can be an error. For the distilled water used tap water here. Conclusion:- According to the graph the concentration of the unknown solution is found to be a

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done
