Biology Fermentation Practical "A comparison of the respiration of yeast in different sugar substrates" Aim: The aim was to compare the respiration of yeast in different substrates of sugars‚ i.e. between a monosaccharide (glucose) and a disaccharide (maltose) Theory: There are three types of Carbohydrates‚ monosaccharides‚ disaccharides‚ and polysaccharides. The two‚ which I will be looking at‚ are‚ monosaccharide (glucose) and the disaccharide (maltose) Classification and major properties of

The plan was to obtain an angiogram to check patients’ blood flow; however he was discovered on admission labs to have acute on chronic renal failure‚ patient states he is unaware of kidney problems before. He states he is able to pass his urine without difficulty‚ no obstructive symptoms‚ no history of kidney stones‚ no urinary tract infections‚ no hematosis

biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis usually enter into the citric acid cycle and the electron transport chain to produce more energy. Fructose enters the glycolytic pathway through the liver or skeletal muscle. For example‚ in the liver‚ fructose

Writing of Lab Reports __________________________________________________________________________ W hy should I bother writing lab reports in the correct way?” The Foundation Programme is designed to prepare you for undergraduate studies at UTAR which will require the writing of lab reports all years generally. At the end of your third year‚ you may have an opportunity to work on scientific projects which will culminate in an official scientific report. Depending on the quality of your report

The experiment we conducted in lab used three different species of algae‚ Macrocystis (brown)‚ Plocamium (red) and Ulva (green). Before we conducted anything‚ we first measured the initial oxygen concentration in the water that was used to house each alga. This was done because in the water that we used there happened to be phytoplankton which can respire and photosynthesize. If we didn’t take them into consideration our results would end up skewed. Once that was known we took a piece of each algae

possible causes of reduction in air flow to the lungs? An allergic reaction could cause the trac to swell‚ restricting the flow of air. An obstruction could also block the trachea decreasing or blocking the air flow as well. Factors Affecting Respiration Activity 4: Effect of Surfactant on Respiratory Volumes 1. When surfactant is added‚ what happens to the tidal volume? It increases the amount of air being inhaled. 2. As a result of the tidal volume change‚ what happens to the flow into
