Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

Introduction Over the course of several weeks‚ myself and my fellow classmates have been researching and conducting an experiment that focuses on the effect of ascorbate peroxidase (a.p) as well as salt stress at different levels of concentrations on Abelmoschus esculentus (okra). Okra is a plant that is composed of 87.1% of water. In addition to being made mostly of water this highly nutritious vegetable is also composed of 0.2% of fat‚ 9.7% of carbohydrate‚ 2.2 % protein‚ 1.0 % fiber‚ and 0

The Sperm and the Egg Melanie Chapman PSY/265 June 27‚ 2013 Sally Henzel The Sperm and the Egg Eggna‚ one of the many‚ many‚ millions of eggs produced while still in the fetal ovaries is finally able to make the journey and become fertilized. It has been twenty some odd years in the making. This long‚ overdue journey means she will soon be meeting up with Spermy‚ the lucky sperm who will assist Eggna in forming a new life. Spermy‚ the selected lucky sperm that was chosen for the mission

Minnie’s Breakdown In “A Jury of Her Peers”‚ it is difficult for the reader not to be thrown into the mindset of Mrs. Wright. Minnie Foster Wright was a sweet woman who died over a 20 year period. This story shows how belittled women were in these days. The two women who joined their husbands to witness the scene were privy to every scornful thing the men had to say about Minnie’s upkeep of the place. What the men didn’t realize is that the only evidence they could possibly find to convict Minnie

Title: The Effect of Adjusted Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen

EXPLORING THE EGG CELL By: Christina Vu SNC2D3 Mr.Ram FUNCTION OF THE EGG CELL: The egg cell is the female gamete used for sexual reproduction. The egg cell is responsible for providing half of the genetic material required for reproduction. When the egg cell joins with the sperm cell.... The egg cell is large and bulky structure which allows the sperm cell to get in easily. WHAT ORGANELLES DOES AN EGG CELL HAVE AND THEIR FUNCTION? Mitochondria: Produces energy for the cell by a process

Enzyme Catalysis Abstract: Catalysis is an enzyme that decomposes hydrogen peroxide into oxygen and water. In this lab we will conduct a series of experiments to determine the affects of; pH‚ temperature‚ and concentration change on such catalysis. After completing the experiments we determined that catalase works most efficiently when in a 27°c‚ 50% (5 ml of catalase – 5ml of water)‚ and a normal body pH of 7°.

Eggs in a pan (Oeufs sur plat) is a still life painting by french artist Antoine Vollon. It is an oil painting on canvas depicting four eggs and their yellow yolks in a pan‚ sitting on a shelf or bench next to a pitcher of (presumably) water or milk. It was painted in the period between 1885 and 1890 and is now a part of the permanent collection of the National Gallery of Victoria. The artist‚ Antoine Vollon‚ was born in France in the year 1833. He focused primarily on still life painting but

The Sperm and the Egg PSY/265 August 26‚ 2011 The Sperm and the Egg The main function of the sperm cell is to locate an egg‚ and fertilize it forming a zygote. Sperm cells are believed to have a sense of smell in which they use to locate the egg which is one of the clue factors sperm cells use‚ sperm cells do not just swim around randomly before locating an egg to fertilize. In the females reproductive tract it becomes warmer as the Fallopian tubes are neared. That is also another clue factor

August 2011 Title: Creating the chemical reaction of Osmosis with an Egg. Purpose: We are taking a large single cell (the egg) and demonstrating Osmosis. Osmosis is a type of diffusion where the water molecules is the solution that is being moved. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. Introduction: When trying to create an osmosis reaction‚ it is important
