A Macromolecule is a molecule with a very large number of atoms .The word macromolecule is usually used for describing polymers. Molecules that are made up of smaller molecules are called monomers‚ there are also Organic Molecules composed of carbon atoms .The functions of the Four big Macromolecules: First‚ Carbohydrates‚ carbohydrates is the function of being used for energy production during cellular respiration. Second ‚ Lipids‚ lipids are used for four things; insulation and long-term energy

compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size. Atoms have diverse characters that depend on the atoms electronic configuration. Carbons unique configuration allows it to form bonds with up to four other atoms‚ and gives carbon a covalent compactivity with many other

explain why 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

BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide

Through the studies already observed‚ rabies was transmitted through the bite of a rabid animal‚ and that the incubation period varied from a few days to several months. Beyond this‚ nothing definite was known. Then M. Bouley‚ a professor of veterinary science‚ noted a germ or organism in the saliva of a rabid dog. Pasteur confirmed Bouley

The Four Main Macromolecules Interestingly enough‚ all cells that build up an entire organism‚ such as the human body‚ only consist of water‚ inorganic ions‚ and organic compounds as three dominant components. Together‚ water and inorganic ions such as Sodium‚ Magnesium‚ Calcium‚ Phosphate‚ etc. make up around 70% of the cell’s mass‚ while organic compounds make up the rest. Unlike its other two counterparts‚ organic compounds contain carbon-hydrogen reactions that allow them to create‚ sustain‚

In the past‚ animal testing has often contributed to human kind and was most of the time accurate‚ but as we progress‚ we slowly dive into the smaller details‚ that we as humans differ completely from animals. Small intricate things such as single gene markers‚ that maybe both humans and primates have‚ but respond differently to differently things can drastically change the results of a test. A research center called National Anti-Vivisection Society (NAVS)‚ has recently does a study‚ “Which compared

which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing with the four organic molecules are proteins. Proteins provide structure and function and have the chemical structures of Carbon

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals Brianne Simonsen Lab Section 8 4 Oct. 2005 Abstract In this experiment the oxygen consumption of a mouse in environments of varying temperatures was studied. The hypothesis behind this experiment was that more oxygen would be consumed at a lower temperature to maintain body heat. To measure the rate of oxygen consumption a mouse was given a specific amount of oxygen. The amount consumed in a specific time was measured and
