BASIC CHEMISTRY (UDBB 1114) BACHELOR OF SCIENCE (BIOTECHNOLOGY) SESSION : MAY 2013 DATE : 25 JUNE 2013 LECTERUR : EXPERIMENT 4 DETERMINING MOLECULE WEIGHT BY FREEZING POINT DEPRESSION METHOD STUDENT NAME : ID : LAB PARTNERS | | INTRODUCTION According to Anne‚ n.d‚ the freezing point of a liquid is decreased by adding to another compound to it. This is known as freezing point depression. The pure solvent will have higher freezing point than the solution. Colligative property of

controlled through conformational changes at the protein level. The other mechanisms used to control aquaporin water transport is through changing the density of the aquaporin at a specific membrane. The second mechanism listed involves trafficking in which proteins are alternated between target

and horrible deaths of buring at the stake‚ hanging‚ or being tortured. The estimates of people killed ranged up to the millions which included men‚ women‚ children‚ and even aristocrats as they were accused of witchcraft. Although‚ poor and elderly women were the ones effected the most from multitudes of paranoia and delusions in those centuries. However‚ certain molecules played a role in this discrimination that ultimately led millions to their demise. Toil and Trouble Witchcraft‚ prior to 1350

Molecular shapes play a part in how close two molecules can come to each other as when water molecules provide a solvent for other organic molecules. Cells are dynamic structures with constant activity The carbohydrates are unique in forming long chain polymer and also branching these chains. This is more complicated than protein where only 20 amino acids can form a long single chain. Here there can be numerous kinds of bonding forming a straight chain or long chain polymer. More over the number

organic compounds are carbohydrates‚ lipids‚ nucleic acids‚ and proteins. Each which are made up of elements and monomers. Each organic compound has it’s own function and chemical structure. Each compound also plays a role in living organisms. Carbohydrates are composed of several elements‚ and one monomer. The elements include: carbon‚ hydrogen‚ and oxygen atoms. Carbohydrates are composed of only one monomer‚ which is monosaccharides. Monosaccharides are the simplest carbohydrates‚ and are required

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein. According to the DNA and protein article DNA is used in many things but DNA is used to make pol-peptides. They are another word for proteins. When a cell makes a protein the direction are resembled from the part of an DNA. DNA strand and transcript

digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down into small molecules that can then be absorbed

Respiration  Cellular respiration is the process of oxidizing food molecules‚ like glucose‚ to carbon dioxide and water. C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2 The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis‚ the breakdown of glucose to pyruvic acid the complete oxidation of pyruvic acid to carbon dioxide and water In eukaryotes‚ glycolysis occurs in the cytosol.
