my organism. First off Yeast is a microscopic fungus consisting of single oval cells that reproduce by budding or fission (is the splitting of an atom)‚ and capable of converting sugar into alcohol and carbon dioxide. When making your own bread‚ you can buy yeast in the grocery store. The yeast contains little brown grains that will carry out cellular respiration and grow when put in water with sugar. In order to conduct the lab the specific thing that I’m looking at‚ when it comes to respiration in

the use of protein catalyst called enzymes‚ that help speed up chemical reactions within the body without being denatured in the processes. Enzymes can be used continually by temporary binding to a specific substrate in the active site to convert the substrate into a product that the cell needs to perform a specific function. Without the use of catalyst enzymes‚ homeostasis wouldn’t be able to occur quickly enough which can result in many bodily functions unable to work properly. The focus of this

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

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best

about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction1 in EP6.4 and then in AA2.1. I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: Investigate the effect of concentration for each reactant and use the results to find the rate equation for this particular

Introduction The 1980s witnessed a surge in popularity to examine the concept of organizational culture as managers became increasingly aware of the ways that an organizational culture can affect employees and organizations. This interest led management scholars and practitioners to undertake research investigations resulting in numerous articles‚ including a complete issue of Administrative Science Quarterly (September 1983)‚ Organization Dynamics (Autumn 1983) and Journal of Management Studies (May
