Materials: 30 drops of monosaccharide solution (2) 30 drops of disaccharide solution (2) 30 drops of polysaccharide solution (2) 30 drops of unknown solution #10 (2) test tube (4) hot plate 30 drops of Benedict’s solution (4) 3-5 drops of iodine (4) beaker (for water bath) Procedure: Number test tubes 1-4. Add 30 drops of each saccharide solution (monosaccharide solution in 1, disaccharide solution in 2, polysaccharide solution in 3, unknown

to detect the glucose monosaccharide. Now, according to the lab protocol, cow milk main sugar is lactose, rice milk is glucose (immediately detected by glucose test trip), and soy milk is sucrose (not affected by lactase). Lactose is the only disaccharide that is broken down by lactase, which releases the glucose monosaccharide recognized by the glucose test strip. Question 2 Lactose is a disaccharide as per Nelson & Cox (2008). This sugar is made of two monosaccharides: glucose and galactose

of oxygen consumed, or the amount of CO2 given off can be measured. Bread, wine, and beer are all made from yeast. Yeast must go through cellular respiration and produce CO2 in order for the bread to rise and form properly; however, different monosaccharides may affect the level of CO2, measured in mL, given off by Saccharomyces cerevisiae (found in yeast), while affecting yeast’s ability to metabolize during glycolysis. Durham tubes (a sealed, cut-off 5 mL, pipette) can be used to measure the amount

Water Water is a medium for metabolic reactions and an important constituent of cells. In most plants and animals, it makes up about 65-95% of their mass. The water molecule is referred to as a dipole, a polar molecule, with a positive (hydrogen) and negative (oxygen) charge, separated by a very small distance. A molecule with a separated charge is polar. A hydrogen bond; the weak attractive force between a hydrogen atom with a partial positive (o+) charge and an atom with a partial negative charge

A macromolecule consists of more than 1000 atoms. They are constructed by what is known as polymerization. Polymerization is a process where smaller individual subunits called monomers are linked together in a chain to form a larger molecule. That large molecule that was formed by polymerization is what we call a macromolecule. There are four types of macromolecules, lipids, proteins, carbohydrates, and nucleic acids. Those four macromolecules are fundamental for living, but for this lab we will

Mia Dennings Ms. Hardison Biology 30 October 2017 The Effects of Sugar with Yeast Could the effects of sugar with yeast vary depending on what sugar you use? Monosaccharide, disaccharides, polysaccharides are the three main categories of sugar. Yeast mixed with each different sugar will all have different outcomes. Positive and negative effects are both present in all three mixtures. Which sugar has the best effect? Yeast, a living bacteria, is used in baking to help the dough rise. The dough rising

cranberry juice would not easily partake in fermentation because of the artificial sugar sucralose that is present. The third hypothesis was that the respirometer containing carrot juice would take much longer to undergo fermentation in comparison to monosaccharides because of the complex carbohydrates sucrose and starch present. The last hypothesis was that the respirometer containing grape juice would have a higher rate of fermentation than the other respirometers because of the simplicity of the

and living tissue. All carbohydrates consist of carbon, hydrogen, and oxygen. Simple sugars, known as monosaccharides, are the monomers of carbohydrates. This means that they are the building blocks for all carbohydrates. Examples of monosaccharides include glucose, fructose, and galactose. These sugars are combined to form disaccharides, or two sugars. Disaccharides form when two monosaccharides bind using the process of dehydration synthesis. Examples of disaccharides are sucrose, maltose, and lactose

Phase 2 & 3: Analysis/discussion phase: Introduction: Cellular respiration is undergone by most living organisms to gain chemical energy, in the form of adenosine triphosphate (ATP). This energy is produced via three stages of cellular respiration; glycolysis, citric acid cycle, and the electron transport chain. Glycolysis and the citric acid cycle are both anaerobic pathways because they do not need oxygen to form ATP, and the electron transport chain is aerobic as this process occurs in the
