1B.5 Inorganic ions

Cards (11)

  • what are hydrogen ions used for?
    they affect pH (a measure of the concentration of H+ ions) and therefore all enzyme controlled reactions.
  • what are iron ions used for?
    they bind oxygen to haemoglobin.
  • what are inorganic ions?
    ions that don't contain carbon (minus a few exceptions).
  • what is an ion?
    an atom with an electric charge.
  • what is a cation?
    a positively charged ion.
  • what are phosphate ions used for?
    the bonds between phosphate groups in ATP store energy, and they can be used for phosphorylation (reacting with other compounds to increase their reactivity).

    Joins nucleotides via phosphodiester bond in the backbone of DNA/RNA/in nucleotides.

    They form the Hydrophilic water soluble part of phospholipid bilayer membrane.
  • name four examples of inorganic ions.
    iron, phosphate, hydrogen, sodium.
  • where are inorganic ions found?
    in solutions, in the cytoplasm, in bodily fluids.
  • what is an anion?
    a negatively charged ion.
  • what are sodium ions used for?
    they co-transport glucose and amino acids into the blood.
  • suggest how high sodium concentrations in the medicines taken could affect blood volume.
    Sodium Ions lower blood water potential
    water moves in via osmosis from tissue fluid
    blood volume increases
