activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less

essentially the building blocks of protein. There are 20 different kind of amino acids that form protein but only three of them are essential for humans. those three are phenylalanine‚ tryptophan‚ and valine. These amino acids make up about 75% of the body and the essential amino acids need to be ingested every day or else protein degradation can occur. 2) List all of the roles proteins have in our bodies. page #202 There are many different type of proteins that are configured for different kinds

assumptions about her protein needs are unrealistic based on her current weight. Erin’s protein consumption is too low for her weight. This is roughly 13% of her kcalorie intake which is closer to the lower end of the ranges of 10-35 percent. This is unrealistic because she is not consuming enough calories of protein for her weight. If you calculate her weight by height you can clearly she needs more protein. Erin’s weight 118lbs /2.2ib/kg= 54 kg‚ so know take 54kg x 0.8g/kg= 43.2g protein. (Understanding

Change in Pressure and Different Depths in a Static Fluid Lab Marcus Uchaker MET: 2050 January 26‚ 2012 Purpose: The purpose of this lab is to devise a correlation between that of the data we have collected from our experiment and compare it to that of theory. In this experiment 3 different tests were done in order to test this theory. The first test was to tie a balloon on the end of a manometer and measure the pressure at different depths in a large beaker filled with water. The next

Understanding the Functions of Proteins and DNA Ingrid Waldron‚ Biology Department‚ University of Pennsylvania‚ 2012 These key concepts and activities are suggested as part of an introductory unit on biological molecules (or as an introduction to a unit on molecular biology). The overarching goal is to help students understand that proteins and DNA are not just abstract concepts in biology textbooks but rather crucial components of our bodies that affect familiar functions and characteristics

Introduction: The purpose of this experiment is to test if altering the pH of the milk will trigger a hydrophobic reaction. It will also give me a better understanding of the scientific method‚ hydrophobic reactions‚ and how pH affects substances. If the vinegar and salt are added to the heated milk‚ then the milk will curdle. I came to this conclusion based on common knowledge and the text introducing the experiment. I have not made cheese at home before‚ but I have made Hamburger Helper meals
