Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

Effect of temperature on enzyme activity In this experiment… Independent variable: Temperature of the amylase Dependent variable: Enzyme activity which is measured by the time for disappearance of starch Controlled variables: Volume of amylase; volume of starch solution; concentration of amylase; concentration of starch solution Prediction of results i) At low temperature‚ the rate of amylase activity is very low. ii) At optimum (=best) temperature‚ the rate of amylase activity is the highest

THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

Temperature affecting enzyme activity Aim: To see how temperature can affect enzyme activity Prediction:-I think the one that will work best will be the rennin placed in milk at 37oC My independent variable will be the temperature My dependant variable will be how thick the milk becomes The equipment I need is milk‚ 5 test tubes‚ rennin‚ water bath‚ boiled rennin‚ a glass rod and a stopwatch Introduction: Rennin is an enzyme found in the stomach‚ its function is to solidify milk.

After the Atlantic slave trade ended in 1808‚ great pressure was put on May lands Eastern Shore to provide slaves for the cotton fields in the Deep South. "Minty" then chose her mothers name which was Harriet and her husbands last name which was Tubman. When her master died‚ she made a decision that could change her life forever. "I had reasoned this out in my mind; there was one of two things. I had

That is what Harriet Tubman’s life was like for 11 years of her life. Harriet Tubman was born in 1822 in Dorchester County‚ Maryland. Her original birth name was Araminta Ross and she was born into slavery. In 1844‚ she married a free black man named John Tubman. This led to her changing her name to the name we all know as Harriet Tubman. Harriet then got fed up with all of this slave work and she escaped from Bucktown‚ Maryland to Philadelphia in 1849.

Harriet Tubman was born in Dorchester County‚ Maryland in the year of 1822. Harriet Tubman grew up with a very loving mother‚ but the first years of her life were pretty tough‚ though. She lived with a fear of getting separated from her family‚ like many other slaves. Harriet’s real name was Armanitia Ross‚ but she changed it. Harriet was a humanitarian to all slaves by taking care of them; being a nurse‚ and helping them reach free land through the Underground Railroad. Harriet’s greatest achievement

She was work at the field and hauling logs at the age of twelve. Minty Ross married a free black man and became Harriet Tubman. In 1849 tubman made a life changing decision to run away unable to convince her husband to come with her. Her husband also said “if you run away I will turn you in”.‚but she took off on her own.

Glucose Oxidase and Its Various Uses Aaron Truong Since glucose oxidase has an end product called hydrogen peroxide‚ which is a harmful substance to bacteria‚ it can be used to fight bacteria‚ or sterilize objects (can have various uses such as in hand sanitizers‚ toothpaste‚ soap‚ etc)‚ not just biosensors. Another key part in the reaction would be C6H12O6‚ or glucose. Glucose oxidase can be applied to diabetics as mentioned earlier‚ as biosensors work by "keeping track of the
