The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such as

How Enzymes work in the home and in industry essay This essay aims to explore the ways on how enzymes are used in home and in industry‚ and it aims to explain the advantages and disadvantages of using enzymes in the home and industry. An enzyme is a protein that is formed by the body that acts as a catalyst to cause a certain desired reaction. Enzymes are very specific. Each enzyme is designed to initiate a specific response with a specific result. Firstly‚ the AQA Science Biology textbook published

experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are made up of proteins which

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

ENG 111 Silent Killer The liver helps digest food‚ absorb nutrients and expel toxins from the body. Recent studies show that one in ten children in US is thought to have a liver disease that was thought to afflict alcoholic adults. The condition has become very common in non-drinkers that it has been dubbed nonalcoholic fatty liver disease. Whenever someone gets the disease‚ the organ becomes bloated and discolored due to the fatty cells. This disease is alarming doctors because it progresses

Recombinant plasmids are when DNA fragments are inserted into a plasmid vector. The recognition site is where the plasmid gets cut by the restriction enzyme which is an enzyme that cuts a DNA molecule. Recombinant DNA is the DNA being inserted into the E.Coli. The purpose of the lab is to see if we can make the E.Coli glow and resistant to ampicillin. In the lab we were transforming a north american jellyfish by the name Aequorea victoria to produce GFP‚ which is a fluorescent protein which causes them

Headline: Abnormal Liver Enzymes: What Does It Mean? Keywords: Liver‚ increase‚ enzymes‚ symptoms‚ test Page Description: Elevated liver enzyme is a condition in which there is an increase in the leakage of chemicals i.e. liver enzymes through liver cells. This hike leads to symptoms of various health problems. Blood test can be used in determining the associated causes and symptoms. Text: { What is meant by Elevated Liver Enzymes? Elevated liver enzymes are a common problem. Inflammation or

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

The Effect of Different Concentrations of the Enzyme Catechol Oxidase on the Rate of Benzoquinone Production When Mixed with Pure Catechol Carson Levine November 4th‚ 2013 Abstract Catechol oxidase is an enzyme that speeds up the oxidation reaction when catechol is exposed to oxygen. When the reaction occurs‚ benzoquinone is produced turning the oxidized substance brown. It was hypothesized that the higher the concentration of catechol oxidase‚ the browner the
