Resource summary

IB SL Biology: Chemical Elements and Water
  1. Most frequently occurring chemical elements in living things
    1. Carbon
      1. Hydrogen
        1. Oxygen
          1. Nitrogen
            1. Other necessary elements
              1. Sulphur
                1. Needed for synthesis of two amino acids
                2. Calcium
                  1. Acts as a messenger by binding to calmodulin + other proteins which regulate transcription + other processes in the cell
                  2. Phosphorus
                    1. Part of DNA molecules
                      1. Part of phosphate groups in ATP
                      2. Sodium
                        1. Raises solute concentration in cytoplasm which causes water to enter by osmosis
                        2. Iron
                          1. Synthesis of cytochromes (proteins used during electron transport for aerobic respiration
                      3. Properties of water
                        1. Thermal
                          1. Large HC: much energy needed to break hydrogen bonds
                            1. temperature generally remains stable
                            2. High boiling and freezing points
                              1. Due to strong hydrogen bonds
