Measuring the efficiency of various carbohydrate substrates in yeast fermentation. Cherrishe Brown October 3‚ 2007 Dieldrich Bermudez BSC 2010L Sect# 0560 Discussion As expected in the experiment Glucose‚ Fructose‚ and Sucrose were all utilized for fermentation. Based on the rate of evolution of CO2 the yeast was most efficiently able to utilize the substrate Glucose‚ followed by Sucrose and Fructose respectively. Given more time I believe that Sucrose would have surpassed glucose in total

us and the environment. We used Nutrient Agar which is a growth medium used to culture microorganisms or small plants and Sabourand Dextrose Agar plates used to cultivate moulds and yeasts. The objective of it was to demonstrate that microbes are everywhere. We expected to find a variety of bacteria‚ moulds and yeasts. We were introduced to aseptic techniques as they help ensure that only certain microorganisms are present in the plate. These methods also guarantee that microorganisms do not escape

Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

CELL INJURY: CAUSES OF CELL INJURY‚ MECHANISMS OF REVERSIBLE AND IRREVERSIBLE CELL INJURY. CELL INJURY. Causes of cell injury range from gross mechanical external causes to mild endogenous causes as genetic lack of enzymes etc. Virtually all forms of tissue injuries start with molecular or structural alterations in cells. Under normal conditions‚ the cells are in: ❖ homeostastatic „steady“ state Normal cell is confined to relatively narrow range of functions and structure by

Aim To determine the water potential of potato tuber cells. Background knowledge Osmosis is defined as the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. Osmosis is considered in terms of water potential and solute potential. Water potential is a measure of the kinetic energy of water molecules. Here‚ water molecules are constantly moving in a random fashion. Some of them collides with cell membrane

Biology Lab Report Investigating Alcoholic Fermentation and the Affects of Yeast on Dough Aim: The aim was simply to investigate whether or not yeast had any affect on causing dough to rise when baked and to experiment with alcoholic fermentation eg. to see if it gave off carbon dioxide. Introduction: Following a few weeks of fermentation theory‚ groups of three to four were assigned and told to conduct a series of experiments involving the affects of fermentation. My group consisted of
