An Experiment to Test the Effect of Temperature on the Rate of Photosynthesis in Green Algae Background Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight‚ carbon dioxide (co2)‚ and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose

Proteins in Solution by Spectrophotometer Lab bench# 1 Introduction: Absorption spectroscopy is a common method for finding the concentration of proteins or protein complexes in a solution. Proteins absorb light at specific wavelengths and can be defined by the equation A = log (Io/I). This equation states that an absorbance at a specific wavelength‚ A is equal to the log of the ratio of incident light intensity (Io)‚ to transmitted light intensity (I). A spectrophotometer can be used quantitatively

This experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity‚ then more oxygen and glucose molecules will be produced‚ and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of

Morgan Sindall business in a variety ways is related to the rise in interest rates .It may lead to less investment by the private sector as the cost to finance the building would go up so Morgan Sindall might have fewer projects and the income might decrease because interest rates will increase‚ the cost to finance the building would go up. Morgan Sindall will reduce the amount of people working and the employment rate will be decrease. It will affect them in a positive and negative way‚ the advantage

Abstract A spectrophotometer’s purpose is to use colors of the light spectrum to determine the concentration of light absorbing molecules in a solution. (p.59) In this particular lab‚ our mission was to determine the protein concentration and the standard curve of the unknown sample of BSA. This‚ by preparing five dilutions of

Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

Introduction Spectrophotometer is an optical instrument that measures and shows how much light energy is transmitted by a substance in solution at different wavelengths of radiant energy. Light passes into a monochromator where only a very narrow range of wavelengths can pass through. From there‚ light is transmitted through a sample solution‚ and on to a phototube where the light energy is converted to an electric current that is registered on a meter. To measure the amount of light absorbed

and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical and biochemical reactions of photosynthesis and cellular respiration

This essay is a reflection of my first clinical simulation‚ using Driscoll’s (2000) reflection model. For this simulation I took the role of measuring blood pressure. According to the Royal College of Nursing (RCN 2015) blood pressure needs to be checked to identify how much the blood exerts on the walls of the blood vessels. The blood pressure is checked as a routine‚ along with the patient’s temperature‚ pulse and respiratory rate (vital signs). For this scenario my colleague and I entered the
