The Building Blocks of In your table groups make as many observations as you can about the diagram on the left. Biomolecule Look at the biomolecule description cards in the envelope at your lab table and without using your notes, do your best to group them using the characteristics on the cards Everything – whether it’s a rock, frog or a flower is made up of substances called elements. Those are the things that we found in the periodic table. Of the naturally occurring elements on earth, only about 25% are essential to living organisms. In fact, only four of the elements Carbon, Hydrogen, Oxygen & Nitrogen together make up more than 96% of the mass of a human body. Most matter in your body that is not water is made of what we call organic compounds. Organic compounds contain carbon atoms. There are four principal classes of organic compounds found in all living things: Without these compounds, cells could not function. What chemical elements make up these molecules? They are made up of building blocks called monomers, but what are they? What are some examples of these biomolecules? What is their function? Biomolecule Elements its made from: Monomers (building blocks): Last week we researched these biomolecules and and record Biomolecule our findings Elements its made from: in our Monomers (building blocks): notebooks Examples: Examples: Functions: Functions: Chemical structure: Chemical structure: Carbohydrates Elements its made from: C, H, O Monomers (building blocks): Monosaccharides Examples: sugars, starches, glycogen, cellulose Functions: main source of energy for cells Chemical structure: Lipids Elements its made from: C, H, O Monomers (building blocks): Fatty Acids & Glycerol Examples: Fats, oils, waxes, steroids Functions: Long term energy storage, major component of cell membrane Chemical structure: Proteins Elements its made from: C, H, O, N Monomers (building blocks): Amino Acids Examples: Muscles & enzymes Functions: Structure, regulates cellular processes & chemical reactions Chemical structure: Nucleic Acids Elements its made from: C, H, O, N, P Monomers (building blocks): Nucleotides Examples: DNA & RNA Functions: Stores and transfers genetic information Chemical structure: Biomolecule Now return to your lab groups and check your findings. Are there any changes you want to make? We use bridge maps like the one below to show relationships between concepts Birds Bears Nests Caves Bricks Polymers Monomer We use knowledge of biomolecules and their building blocks to complete the multi-bridge map above.
