What happens in diabetes? Lack of insulin or a resistance to insulin is known to have major metabolic effects. Food powers our bodies. When we eat food‚ most digestable carbohydrates are converted into glucose and rapidly absorbed into the bloodstream. We use this glucose for energy. However these carbohydrates cannot be utilized effectively and excess glucose cannot be stored in the liver. The glucose level in the blood increases but the cells of the body will be lacking of glucose and energy.

Factors that Affect the Rate of Reaction of Peroxidase Purpose: To determine the effect of various factors on the rate of reaction between an enzyme and its substrate‚ and also to determine the optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the

Melissa Carrithers AP Chemistry 12/17/14 Rate Law Determination Pre-Lab Purpose: The purpose of this lab is to observe the reaction between sodium hydroxide and crystal violet so that the order of the reaction could be determined along with the rate constant‚ k‚ and the half-life for this reaction. Hypothesis: If the reaction between crystal violet and sodium hydroxide reacts appropriately‚ then the order will be first order. Procedure: Mix 10 mL of sodium hydroxide and crystal violet solution

defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic respiration while the process

8/5/15 Federal Funds Rate Increase According to our textbook in Chapter 12‚ the federal funds rate is "The interest rate financial institutions charge each other for overnight loans used as reserves. A change in the federal funds rate reflects changes in the market demand and supply of excess reserves." I found the best explanation of the federal funds rate at http://www.investopedia.com/terms/f/federalfundsrate.asp. Investopedia defines it as "the interest rate at which a depository

What Happens Next Caitlyn Smith I woke up early one day. The cave was dark and I could not see. I went outside to see if I could find mother‚ but she was nowhere to be found; I guess she went off somewhere without telling me. I’m looking around after just waking up and I see this creature. I don’t know what to do. He comes closer‚ what am I supposed to do? I saw him running towards me and I started getting scared. He grabbed a stick and threw it towards me as if to warn me that he was

Date: 14th-15th October Title: The effect of the concentration of hydrogen peroxide on catalase Aim: to examine how the concentration of the hydrogen peroxide affects the rate of reaction Hypothesis: The substrate concentration will determine the rate of reaction. The reaction will increase as the concentration increases‚ but from a certain concentration‚ the rate will maintain the same rate Materials: 3% hydrogen peroxide 6% hydrogen peroxide catalase round metal basin measuring cylinder

Determining Order from Rates of Reactions AP Chemistry Purpose The focus of this experiment is to recognize that when aqueous solutions of potassium iodate ion (KIO3-) and bisulfite ion (HSO3-) are mixed‚ a series of reactions will occur‚ and the final reaction is signaled by the appearance of a dark blue color. My partners and I investigate how the concentration of the reactants affects the rate of reaction. The purpose of this lab is to find

variables of reactions to determine what increases/decreases reaction rates. The variables we used are hot/cold and room temperature water‚ a equal mixture of HCL and water‚ A equal mixture of NaOH and water‚ either a whole‚ broken‚ or finely crushed Alka-seltzer tablet. The fastest rate average was at 0.04 s (finely crushed Alka-seltzer with room temp. water). The slowest rate average is 8.02 s (Alka-seltzer with cold water). Introduction The theory of this experiment is to determine what factors
