Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in the cells of the body

In this article we have discuss on how we have influenced our natural environment. Our natural environment has being eg; Polluted with the mount of rubbish we have dumped in our ocean which cause water pollution. Deforestation has being a worst nightmare for the animals that live in that habitat. Recycling‚ is a good thing to help save the earth‚ from reducing; paper‚ bottles‚cardboard etc‚ without damaging it from polluting and cutting down trees. Pollution has been a very big concern in our

When Cherry Valance‚ said things are rough all over‚ she meant that the Soc’s weren’t just what was displayed to them on the outside‚ and during the fights‚ they are also people that have lives‚ and families‚ and friends. When Cherry and Marcia are at the movies‚ the Greasers show up‚ and Ponyboy engages in a conversation with Cherry and she says that‚ “We have troubles you’ve never even heard of”(Hinton 34)Cherry Valance says this‚ because the Socs aren’t just the “rich kids‚ the West-side Socs”(34)

peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of enzymatic activity increases until the optimum pH is reached. Aim: To investigate the effects of different pH levels on reactions

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

to the overwhelming demand of plastic bag production and its effects on our environment‚ our landfills are crammed with these non biodegradable materials. Substances used in the manufacturing brought forth various harmful chemicals which worsen over time. As the destructive compounds such as Chloroflourocarbon were introduced‚ the complete deprivation of the Ozone Layer starts. However‚ scientists and nature preservers alike managed to overthrow this hazard‚ but not entirely. To compensate for the

experiment was carried out to monitor the ability of the Barley Amylase Enzyme to effectively break down starch in solutions that are increasing in neutral pH. To do this the experiment was carried out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions

Discovery Restriction enzymes were discovered 40 years ago during investigations into the phenomenon of host-specific restriction and modification of bacterial viruses. Restriction enzymes protect bacteria from infections by viruses‚ and it is generally accepted that this is their role in nature. They function as microbial immune systems. When a strain of E. coli lacking a restriction enzyme is infected with a virus‚ most virus particles can initiate a successful infection. When the same strain
