Charlene Villanueva - Biology Charlene Villanueva - Biology Starch‚ Glycogen and Cellulose Independent Research A polysaccharide is a long chain of monosaccharide molecules‚ held by glycosidic bonds. They are usually not sweet in taste‚ insoluble in water and often do not produce crystals when water is taken out. Starch Starch is a complex solid carbohydrate‚ consisting glucose molecules held together by glycosidic bonds. It is a storage polysaccharide. They can be found in fruits‚ seeds‚ roots

Test for Starch Introduction and Hypothesis: In this experiment‚ we used iodine to test for starch in certain solutions. Iodine separates starch from polysaccharides‚ monosaccharides‚ and disaccharides. Starch is a curled polymer of glucose and iodine interacts with molecules‚ which changes the color of the molecules to a kind of black color. Iodine does not respond with carbohydrates that are not curled or coiled‚ thus the color stays yellowish brown. A black color result means that starch is current

experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser‚ cited

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Conclusion As we did the research for Apple Company‚ we could found out that Apple Company is well developed in a way of their products and services towards the users. Apple had innovated their products and taking the lead of the other company like Nokia‚ Sony Ericsson‚ LG and so on by its own touch screen hand phone technology selling on market to be one of the most influential in the share market of the nationwide. As to be seen‚ Apple focuses its strength on building up their branding power

University of Phoenix Material Introductions and Conclusions As you begin to write the rough draft of your paper‚ think critically about how you might draw your readers’ attention in a compelling way. Consider how to create a rapport with the audience. For example‚ what areas of agreement may already exist between you and your readers? What does your audience need to make them interested in your topic? Types of Introductions One way to draw in the audience is to grab readers’ attention

On the Kelvin scale‚ 0 degrees is absolute zero‚ the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? __If the temperature is colder the molecules move slower and if the temperature is hotter the molecules move faster.

FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without
