Purpose: The purpose of this lab was to test how objects slightly acidic or slightly basic will affect the way catalase‚ the enzyme tested‚ denatures‚ or breaks down. Hypothesis: If the potato is acidic‚ it will react with the H2O2 more than it will with the raw‚ plain potato because the acid will denature the enzyme faster. The manipulated/independent variable is the raw‚ plain potato while the responding/dependent variable is the other types of potatoes used in the experiment. Materials:

Investigate the effect of concentration on the rate of a reaction Research question: To what extent does the concentration of hydrochloric acid affect the rate of the following reaction: 2 HCl(aq) + CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g) Data Collection and Processing: Table1: Different volumes of Co2 gas produced by Different concentrations of HCL acid. Volume of CO2gas formed from 5 different concentrations of HCL acid ±0.5ml 5 different concentrations of HCL acid (Mol) ±0.5ml Time (sec) ±0

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by
Premium Enzyme Catalysis
Enzymes Enzymes are… * Biological catalysts Lower the energy level needed for a biochemical reaction to occur. This energy level is called activation energy. * Proteins Polypeptide chains made up of 100’s-1000’s of amino acids in a specific sequence. * Do not get “used up” in a reaction The number of “uses” of an enzyme depends on the enzyme. * Work more efficiently at certain optimum temperatures. * They are “reaction-specific”. Each enzyme is included in one reaction.

Factors that Determine the Currency Exchange Rates Exchange rate is often referred to as the nominal exchange rate. It is defined as the rate at which one currency can be converted‚ or ’exchanged ’‚ into another currency. For example‚ the pound is currently worth about 1.824 US dollars. One pound can be converted into 1.824 dollars. This is the exchange rate between the pound and the dollar. There are four types of currencies can be operated‚ which are a floating‚ managed and fixed exchange

Discuss the factors affecting the rates of Conformity Conformity is the process of yielding to the majority influence and it has been researched for the past years by many great psychologists. However‚ evidently how much an individual conforms. Firstly dating back to the experiment of Solomon Asch-1951 whereby he manipulated Sherif’s experiment by making sure the participants’ conformity can be measured without the confounding element of ambiguity. Asch’s experiment initial experiment at the time

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

Factors Affect Communication Process FACTORS THAT INFLUENCE THE COMMUNICATION PROCESS Perception Perception is a process by which the meanings of messages are interpreted. The way messages are perceived is related to a combination of a person’s social and cultural influences‚ gender‚ educational background and knowledge‚ and past experiences (Schuster 2010). This complex mix of influences means that no two people are likely to perceive the same message in exactly the same way. Some of the strongest
