Unit One: Biochemistry Organic chemistry: chemistry of carbon based molecules * Life on our planet is carbon based * All life is carbon based, so to understand how biological processes occur we need to consider organic chemistry Hydrocarbons: molecules that are entirely made from carbon and hydrogen * Carbon you can get a lot of shape (rings etc) * Mostly non-metals (hydrogen, carbon, oxygen etc) make up molecules in our cells * Hydrogen, carbon, nitrogen, oxygen

Unit 1.3 Task 1a Cell membrane – The cell membrane is a biological membrane that’s job is to separate the interior of a cell from all of the cells in the outside environment. It is selectively permeable to ions and organic molecules. It also controls the movement of substances in and out of a cell. The function of the cell membrane is to protect the cell from its surroundings. The cell membrane can be found in plants and animal cells. Cell wall – The cell wall is a very flexible but tough layer that

tissue is destroyed because of the disturbed ion transport, creating a multitude of problems related to pancreatic dysfunction.” (Swierzewski) “In the intestines, the epithelial cells are not able to flush away all of the various secretions and macromolecules from the intestinal crypts (pits in the intestinal epithelium), eventually causing obstruction in both the small and large intestines” (Swierzewski) Poor weight, frequent abdominal discomfort, jaundice, and liver disease are other

Student number: 3003481………………… DNA Paternity testing Two rams at the Easton College farm, a Norfolk Horn sheep and a Southdown sheep escaped from their field and ran in the ewes’ enclosure. The ewes were all Suffolk breed, an old native British breed with excellent lamb growth rate. You were asked to help with identifying the father of the lambs and you decided to try a DNA paternity test with two lambs. http://www.norfolkhornbreeders.co.uk/history.php I Protocol To perform a quick

Plant Tissues A mature vascular plant (any plant other than mosses and liverworts), contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell. Some consist of several. Tissue is a cellular organizational level intermediate between cells and a complete organism. A tissue is an ensemble of similar cells and from the same origin, that together carry out a specific function. These are called tissues because of their identical

What are carbohydrates? Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen that serve as energy sources and structural materials for cells of all organisms. Most organic matter on earth is made up of carbohydrates because they are involved in so many aspects of life, including: • Energy stores, fuels, and metabolic intermediaries. • Ribose and deoxyribose sugars are part of the structural framework of RNA and DNA. • The cell walls of bacteria are mainly made up of

crystallization Name: layan shinanah Subject : chemistry Presented to :Ms. Juline Daibes Date : 13,10,2015 Crystallization definition : to change into a solid form that is made up of crystal to cause (something, such as an idea, belief, etc.) to become clear and fully formed. What Happens During a Crystallization : To crystallize an impure, solid compound, add just enough hot solvent to it to completely dissolve it. The flask then contains a hot solution, in which solute molecules

human race because of it’s incredible structure and variability as well as its role in human side application. II. Body G. DNA is Deoxyribonucleic acid * It is also known as a polynucleotide * It is one of the 3 major macromolecules of life! * It is a complex molecule * It is a anti-parallel double helix – meaning its two opposite sides twirl around and form a parallel twisting molecule * Deoxyribose because the carbohydrate, deoxyribose, is a pentacarbon
