Nucleic Acids

Huge polymers made up of many nucleotides Ex: DNA & RNA

DNA D eoxyribo N ucleic A cid Contains all the genes & info needed for replication & making proteins  genetic code specifies the order of amino acids needed to make every different protein in our body!

DNA Nucleotide  monomer Nitrogenous base: A, T, C, or G Pentose Sugar

RNA Ribonucleic Acid single strand, polymer of nucleotides The “Helper Molecule” needed to put amino acids in correct order to make proteins

RNA Nucleotide  monomer Ribose A,C,G, or Uracil

ATP “the energy currency of the cell” Adenosine Triphosphate Made of adenine + ribose + 3 Phosphate Groups MONOMER important for providing the energy needed for chem. rxns in cells Glucose is converted into ATP ( more “manageable” amt of Energy)

Which bill best represents ATP? Why?

Last two phosphate bonds are unstable & easily brokenLast two phosphate bonds are unstable & easily broken hydrolyzed by water to make ADP + P & release Ehydrolyzed by water to make ADP + P & release E re-formed when another P is addedre-formed when another P is added ATP is the energy source cells “spend” to transport molecules across the membrane, to build molecules, contract muscles, conduct nerve impulses etc!ATP is the energy source cells “spend” to transport molecules across the membrane, to build molecules, contract muscles, conduct nerve impulses etc!
