Abstract: This experimentation was to evaluate absorbance and the reaction rate of an enzyme‚ ’-amylase in starch-iodine solution. We will be testing the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures‚ and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To

Chapter 21: Measuring GDP and Economic Growth Problem: 1 a. Aggregate expenditure: Aggregate expenditure is the sum of consumption expenditure‚ investment‚ government expenditure‚ and net exports i.e. AE = C + I + G + (X – M) In the figure‚ B is consumption expenditure‚ D is investment‚ C is government expenditure‚ and E is net exports. Therefore Aggregate Expenditure = $7‚064 billion + $1‚624 billion + $1‚840 billion + (−$330 billion) which is $10‚198 billion. b. Aggregate income:

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

Hydrogen‚ interpreted from Greek as the water-creator (RSC site). Fundamentally it is by far the simplest element‚ yet it composes virtually all of the visible universe. Hydrogen is not merely omnipresent; in actuality‚ it is the oldest and arguably the most essential corporeality to the creation and sustainability of utterly all in existence. The aforementioned characteristic that hydrogen is immensely crucial to the survival of all lifeforms is supported by the fact that it is the building block

that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of substrate. Enzymes are protein molecule that acts as biological catalyst by increasing the rate of reactions without changing the overall process. They are long chain amino acids bound together by peptide bonds. Enzymes are seen in all living cells and controlling the metabolic processes in which they converted nutrients into energy and new cells. Enzymes also help

Measuring Crime CJA/204 October 9‚ 2013 Richard Pacheco Measuring Crime There are two different instruments used in reporting crime. There are also major crimes reporting program used in the United States. These major crime reporting programs do have a purpose and does give statistical information on crime in the United States. There are a difference between crime rates‚ arrest rates‚ clearance rates‚ and recidivism rates. The information reported about crime rates can be misleading and give

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

The goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus
