Effect of changes in substrate concentration on the reaction rate of an enzyme IB biology Internal Assessment 3/23/12 Research Question: Effect of changes in substrate concentration amount on the reaction rate of an enzyme Introduction: In this experiment‚ the substrate is hydrogen peroxide. The purpose of this investigation is to find out the relationship between the substrate concentration and the rate of reaction. Substrates are molecules that are acted upon by enzymes. For instance

Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

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

The purpose of the experiment was to find out how temperature affects the enzymes activity. For example‚ in Humans if the temperature is too high‚ the individual’s brain enzymes can denature and cause life threatening problems. The opposite can occur as well‚ if the temperature is too low‚ hypothermia can occur and it can be dangerous (Wilson‚ 1996). In the experiment optimal conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature

What is Bullwhip effect? Bullwhip Effect can in short be described as the variability in orders in a supply chain system moving up from consumers to core manufacturers. It is also known as the whiplash or whipsaw effect. The causes of this Bullwhip effect have been identified as:- Demand forecast In any company order is placed with the suppliers based on the demand graph. The order is placed to fulfill the current demand and also keeping in mind any unpredictable sale‚ which is the safety stock

The Wave essay: How Ben Ross’ experiment was successful Ben Ross wants to show his students how Hitler could control Germany without people stopping him and also why people said that they didn’t know what happened during World War II. That is why he decides to make an experiment. I will explain how this experiment was successful. Hitler built a totalitarian movement from which he was the leader. First‚ it is important to know that Hitler was elected by German population and consequently he
