Title of Lab: Preparation and Assay of Phenolase and Peroxidase from Sweet and Irish Potato Hypothesis: Polyphenol Oxidase enzyme activity can be detected by change in colour of solution‚ Inhibitors prevent the reaction of the enzymes with substrates‚ the enzyme is relatively specific. Aim: To design and conduct an experiment to demonstrate enzyme activity of Polyphenol Oxidase and Peroxidase when mixed with catechol‚ caffeic acid‚ pyrogallad‚ tyrosine‚ guacol‚ and water‚ to test the effect of

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

GLADSTONE ROAD AGRICULTURAL CENTRE CROP RESEARCH REPORT NO. 1 TUBER QUALITY AND YIELD OF FOUR SWEET POTATO VARIETIES EVALUATED DURING 2007 Kenneth VA Richardson Department of Agriculture Nassau‚ Bahamas November 2009 ABSTRACT A variety trial was conducted on four sweet potato varieties from April to October 2007 at the Gladstone Road Agricultural Centre. The variety ‘Six Weeks’‚ which is an early maturing variety with white flesh and high dry matter content‚ produced the highest marketable yield

Introduction ‘Bashundhara Tissue Industries Ltd’ (BTIL) is currently the largest retailer if tissue paper products in Bangladesh. This company was established at a time when the use of tissue and allied products was not so common. The advent of these items in the domestic market has tangibly transformed personal hygiene standards of the common people. The BTIL plays a vital role as an important import-substitution industry and has recently begun limited exports. Human Resources Management department

Wet Tissue Strength Tested on Various Tissue Brands Abstract: Wet tissue strength was tested on various tissue brands. The wet strength was shown by seeing how many marbles the wet tissue can hold. Students conducted this experiment to determine if higher priced tissues can hold an increased amount of marbles. This experiment was a blind study‚ with the supervisor of this investigation withholding information of which brand is which and their costs. At the end of this experiment‚ it was concluded

My group and I are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads

Chapter 9: Muscles and Muscle Tissue‚ Lecture Outline: I. Overview of Muscle Tissues (pp. 276–278; Table 9.1) A. Types of Muscle Tissue (p. 277; Table 9.1) 1. Skeletal muscle is associated with the bony skeleton and consists of large cells that bear striations and are under voluntary control. 2. Cardiac muscle occurs only in the heart and consists of small cells that are striated and under involuntary control. 3. Smooth muscle is found in the walls of hollow organs and

Telomerase Reactivation Reverses Tissue Degeneration in Aged Telomerase-deficient Mice Jaskelioff et al.‚ Nature‚ January 2011 This study looked at the effects of telomerase activation on the tissues of prematurely-aged adult mice. The telomerase enzyme‚ TERT-ER‚ is not expressed in the cells of these mice. The group induced (turned on) expression of TERT-ER by exposing mice to the compound 4-OHT‚ 4-hydroxytamoxifen (see definitions on next page). This treatment rebuilt the telomeres in

the other factors is slowing down the rate of enzyme reactions‚ it depends on the concentration of those factors. Since enzymes are catalyst of chemical reactions‚ they are responsible to the activities of cells‚ and they determine the function of tissues and organs as well. In plant cells‚ during photosynthesis‚ enzymes are used in chloroplast to catalyse the processes. In light-dependent stage‚ ATP synthase enzyme is used to generate ATP molecules‚ they can be used in light-independent stage.
