The structure and function of carbohydrates A carbohydrate is an organic molecule containing only Carbon‚ Hydrogen and Oxygen with the general formula Cn(H20)n. They are made up of individual molecules called monomers which are joined together by condensation reactions to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such

MEMBRANE PROTEINS determine the membrane’s function Many diff. types of protein in plasma membrane 2 types of proteins Peripheral proteins-loosely bound to surface‚ not embedded in bilayer Integral proteins-penetrate the hydrophobic core Integral Proteins Transmembrane proteins=integral proteins that span the membrane The hydrophobic regions of an integral protein consists of one or more sections of non-polar amino acids‚ often coiled in alpha functions of membrane proteins Transport Allow

Located in South America‚ the Amazon rainforest covers a span of about 3.5 million square miles in several different countries‚ making it the world’s largest rainforest. Rainforests are characterized by the heavy rainfall they receive which is a minimum of six and a half feet a year. Also‚ they can either be tropical or temperate‚ and they are found on nearly every continent‚ not including Antarctica. They are also composed of several vertical layers. The canopy‚ the uppermost layer‚ is the “tops

Identifying the Rainforest The Mt Keira rainforest is located in Wollongong‚ New South Wales in Australia. The Mt Keira rainforest is what we call a subtropical rainforest. There are four types of rainforest: Tropical‚ subtropical‚ warm-temperate and cool-temperate. Tropical rainforests have generally have a warmer climate than subtropical rainforests. Warm-temperate rainforest are slightly cooler than subtropical rainforests‚ and cool-temperate rainforests have very cool climates‚ i.e. Canada

Rainforests February 18th‚ 2013 Mr. Zanardo AJ D’Orazio CGF 3M Grade 11 Rainforests are the oldest living ecosystems on earth. They only cover about 6% of the Earth surface but they contain more than half of the world’s animal and plant species. Rainforests are described as a tall but dense jungle. It is called a “rain” forest because of the high amount of rainfall it gets per year. There are two different types of rainforests Tropical and Temperate. A tropical rainforest is located

Structure & Function of Plants Review: Plant Structure‚ Growth‚ and Development I 1. How does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant? 2. When you eat the following‚ what plant structure are you consuming? Brussels sprouts‚ celery sticks‚ onions‚ and carrot sticks. 3. Characterize the role of each of the three tissue systems in a leaf. 4. Describe at least three specializations in plant organs and

encloses the contents of the cell and regulates the flow of substances into and out of the cell. Mitochondrion - this feature produces a substance called adenosine triphosphate (ATP) which is the carrier of energy in all cells. Centriole - these two features made of hollow tubules play a key role in cell division. Ribosomes - these small‚ granular features of the cell play a key role in the assembly of proteins. Chromosome - During cell division‚ DNA‚ the genetic material duplicates and forms

Brain Structures and Functions Viviana N. Reyes ESE370: Learning & the Brain (CXI1409A) Instructor: Charisse Jones March 9‚ 2014 Brain Structures and Functions Many are fascinated by the brain and its functions. Our brain is composed of different units and lobes that work together but each part‚ of course‚ has a special function. We all ask ourselves‚ how is it that we learn? Do our senses have anything to do with getting new information into our brain? Technology

Cell Structure and FunctionAbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab‚ I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells.IntroductionThe concept of this lab is producing a replica of an animal cell‚ and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell

Give an account of protein structure and function Protein structure 1 Proteins consist of amino acids joined together (in chains) 2 A protein is unique because of the sequence of amino acids 3 The amino acids are joined by strong peptide bonds 4 to produce the primary structure 5 Further (weak) hydrogen bonding between acids 6 produce the secondary and tertiary structures A maximum of 4 marks can be gained from this section.
