An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

“Cells are the building blocks of tissues and therefore multicellular organisms. Using specific examples‚ describe some of the mechanisms used by cells to provide organisation within tissues containing different cell types.” One cannot adequately contemplate the organisation of tissues‚ let alone organisms. Words fall short when explaining the sheer vastness of their complexity. It is incredible that such astonishingly patterned structures can be formed from so many individual cells but greater

The Guernsey Literary and Potato Peel Pie Society‚ here on forth referred to as TGLS‚ by Mary Ann Shaffer & Annie Barrows was first published in 2008 and is an epistolary novel‚ it was written by Shaffer‚ but because of Shaffer’s death in 2008‚ she asked Barrows to finish the rewriting and editing of the novel. The novel is largely based on historical facts and therefore deals with themes and events that can be considered possible. This Essay will discuss the representations of WWII and concentrate

Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the potato to make the concentrations

do: We will put potato pieces of similar sizes in to test tubes of different concentrations of sucrose solution‚ and measure any changes in mass and length. Affecting Factors: There are a number of factors which can affect our results. We need to keep them all the same‚ and make sure that the only thing that changes is the concentration of the sucrose solution. These factors include: • Starting length of potato • Volume of Sucrose solution • Temperature of potato • Temperature

investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying

Solution for Chapter 2 Exercise 5a 5. a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of The Couch Potato Furniture Company. The manager needs a program to determine the profit on any item sold. Input includes the wholesale price and retail price for an item. The output is the item’s profit‚ which is the retail price minus the wholesale price. Use three modules. The main program declares global variables and calls housekeeping‚ detail‚ and end-of-job

There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions
