From Simple to Complex: The Building Blocks of Life
▪ ____________________________Compounds –contain the element carbon and hydrogen.
▪ ____________________________Compounds – do not contain the carbon and hydrogen together*.
* Is carbon dioxide (CO2) organic or inorganic? ___________________________
❖ The four most abundant elements in living things are ___________________, __________________, _________________ and _______________________ (HONC).
• ____________________________ – such as plants are able to make their own organic compounds from inorganic compounds through photosynthesis (the chemical equation is seen below).
Carbon Dioxide + Water + Solar Energy ( Glucose + Oxygen
6 CO2 + 6 H2O + Solar energy ( C6H12O6 + 6 O2
__________ __________ __________ __________
So today, almost all organic compounds are formed biotically (by __________________ things), then the question became – how did the first organic compounds form?
Miller and Urey Experiment to answer how first organic compounds formed:
Miller & Urey’s experiment provides support for the idea that conditions on lifeless, ‘primordial’ Earth could have allowed the spontaneous formation of more complex (organic) molecules. Since the conditions on earth are now very different, we do not see the same reactions occurring.
Important Terms to know:
❖ ____________________: A single compound or building block used to make a larger compound.
❖ __________________: Many monomers joined together to form a large compound
❖ ____________________________ ____________________________: The process of combining small compounds to form large compounds and water molecules. (Also known as Condensation Reaction)
H+ OH- + H+ OH- = H+ OH- + H2O
❖ _________________________________: Breaking down a larger compound (polymers) into smaller pieces (monomers)… Enzymes and water are needed to break the polymer down.
H+ OH- + H2O = H+ OH- + H+ OH-
