Biology‚ Section G 27 September 2013 Experiment 5.3 Title: The Fragility of an Enzyme Purpose: To see how easily enzyme function can be destroyed. Hypothesis: I think that the bowl with only Jell-O will set as will the bowl with heated pineapple but the Jell-O with fresh‚ uncooked pineapple will not set. Materials: Part of a fresh pineapple A blender or a fine cheese grater 3 small bowls A small box of Jell-O Pot Stove Refrigerator 2 tablespoons Procedure: 1. Cut the pineapple

Potato Enzyme Lab Enzymes are protein catalysts that speed up chemical reaction in living organisms. The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added

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

believe that extra-curricular activities have an effect on teenage drug and alcohol use. I feel that the more extra-curricular activities people are involved in‚ whether those activities are clubs‚ sports‚ dance‚ hanging out with friends‚ community service‚ etc. that those people are less likely to use drugs and alcohol. However‚ the people who are not really involved in extra-curricular activities are more likely to use drugs and alcohol. The more activities and less free times a person has in their

Tiempo’s To Be Free‚ numerous aspects of freedom were emphasized and highlighted. One of them is national freedom‚ as seen in the three different historical periods: the American‚ Spanish‚ and Japanese colonisation. Another aspect of freedom is also highlighted in the personal life of the servant‚ Rubio‚ before and during his wedding. This scene emphasizes the fact that “to be free is to feel free.” (Tiempo 274) In addition‚ it also emphasizes the general theme of freedom in the book: being free was feeling

Are we free to do what we want? Humans are species with highly developed brain‚ intelligence‚ wisdom‚ and self- awareness. We do also have a free will. Does it mean that we are free to do what we want? Does it give us ability and permission to act regardless of any other features? In the topic of this essay we can notice the construction of argument with its hidden premise. The full argument can sound: ‘If we have a free will‚ then we are free to do what we want and nothing can stop us in achieving

They are not merely the puppets in the hands of fate and gods but their own motives surpass over all other influences. if they are performing any action or making any decision by following the gods even at that time their inner feelings and desires are there that compel them to act

I had previously been looking into the effects of free radicals on the body‚ and the types of supplements that would work to inactivate these dangerous toxins. Webster’s Dictionary defines a free radical as‚ “An atom or group of atoms that has at least one unpaired electron‚ and is therefore unstable and highly reactive. In animal tissues‚ free radicals can damage cells and are believed to accelerate the progression of cancer‚ cardiovascular disease‚ and age-related diseases” (Merriam-Webster‚ 2010)

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate
