Core Practical: Enzyme concentrations and enzyme activity. Introduction In this experiment I shall investigate how the enzyme concentration can affect the initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis

Title of Experiment: The Effect of Temperature on the Hatching Success of Brine Shrimps. Abstract In this experiment‚ 40 brine shrimp eggs are put into a test tube containing salt water at different temperature such as 25°C and 35°C respectively. The eggs are left from two days to hatch. After two days‚ the number of eggs successfully hatched are observed and counted. Introduction Brine shrimp is the common name for a primordial crustacean that reaches less than 1.3 cm in length and is usually

are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable at higher temperatures and the shape of the enzyme changes. The enzyme is also used to remove hydrogen peroxide from clothing in the textile industry. This would make sense because when an enzyme encounters a substrate molecule

occur within the cardiovascular system in response to exercise is heart rate. When engaging in exercise‚ the amount of energy required increases instantaneously within the skeletal muscles. This sudden demand creates increasing stress on the cardio-respiratory system to remove the waste products and carbon dioxide from the cells and provide more oxygen for the working cells. This surge of extra energy that is needed requires the heart to pump faster and harder in order to increase the volume of blood

ADVERSE EFFECTS OF PEOPLE ACTIVITIES The Greenhouse Effect Too much carbon dioxide and other gases emitted by factories are accumulating in the atmosphere. These gases allow sunlight to penetrate the earth’s atmosphere but unfortunately‚ they also trap radiant heat and revert its escape into outer space. The immediate consequence is Global Warming‚ which is better known as the Green House Effect The rise in the average temperature of the earth could have serious consequence. Among them is

Given the circumstances‚ dangerously high internal temperatures and high blood alcohol levels‚ Renee would inform the detective of the following physiological information: The vasodilation caused by the consumption of alcohol increases the diameter of blood vessels‚ which increases the volume of blood that can pass through a vessel. This dilation of blood vessels decreases the amount of venous return to the heart. Also‚ this increased diameter of blood vessels and increased volume allows for less

The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

It’s not likely that you will ever read another story about a man who has endured two heart transplants‚ a kidney transplant‚ and numerous other medical and emotional traumas---like you will when reading 1 Man‚ 3 Hearts‚ 9 Lives: A Story of Hope‚ Resilience‚ and Survival by Christophe Lafontant. I was‚ of course‚ intrigued when I saw the book up for review‚ and though it was a harrowing journey in which I felt like I was there with the author experiencing his pain‚ it is a journey I would gladly
