The Effects of Substrate Concentration‚ Reaction Time and Enzyme Concentration on Enzyme Reactions Corey von Ellm-St. Croix Rachael Kwan ID#: 20427841 Matthew Hrycyshyn & Saeideh Mayanloo Biol 130L‚ Section 017 Wednesday‚ 9:30am-12:20pm‚ 151 November 09‚ 2011 A living system controls its activity through enzymes. Enzymes are made from hundreds or even thousands of amino acids connected in a very unique and specific order. Almost all enzymes are proteins‚ except for ribozymes. The chain

during the reaction. (Hudon-Miller‚ Enzymes‚ 2013) Enzymes act as protein catalysts in biochemical processes Frutokinase is the enzyme that acts on fructose in the liver and turns fructose into fructose 1 phosphate. Fructose 1 phosphate is changed to DHAP and glyaraldehyde by an enzyme called aldolase B.

David Kennedy Bio 210 Lab Report 1 10/11/13 Microbial Growth Background Information: This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately

flow will occur and the resistance to flow will be independent of the pipe wall roughness (e). Meanwhile‚ turbulent flow occurs when the value of Reynolds number is exceeding 4000. For large viscous force‚ whereby Re value is less than 2300‚ viscous effects are great enough to damp any disturbance in the flow and the flow remains laminar. The flow is called laminar because the flow takes place in layers. Any combination of low velocity‚ small

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked

Osmosis Lab Research Question: In this lab‚ our goal was to look at the effects of different sucrose concentrations on osmosis in potatoes. Our research question was “How do the sugar levels affect the rate of osmosis in potatoes?”. Background Information: Solutions consist of solutes dissolved in a solvent. In all living organisms there are many different types of solutes including salts and sugars. The major solvent is water. There are different concentrations of solutes in various regions

The glycoalkaloids include solamargine‚ solasonine‚ and solanine that belong to the tropane group of compounds. Jain R‚ Khattak JZ 2012 Solanine’s function and activity has been extensively studied. It comprises 95 percent of the total alkaloid concentration present in the plant and is found naturally in any part. It is one of the plant’s major natural defenses as it is toxic even in small quantities with a molecular weight of 868.04 and formula C45H73NO15. It consists of an aglycone‚ solanidine (alkaloidal

affect the distribution of hydrogen peroxide by the catalase in this organism. In this catalase and hydrogen peroxide experiment‚ we will find out how enzymes act as catalysts by causing chemical reactions to occur. Using a potato and hydrogen peroxide‚ we can observe how enzymes like catalase work to perform the breaking down‚ of other substances. We will look at enzymes and catalase and its substrate hydrogen peroxide. Catalase accelerates the breakdown of hydrogen peroxide (H2O2) into water

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These
