inorganic ions Flashcards
where are inorganic ions found?
they occur in solution in cytoplasm and body fluids of organisms
some in high concentraitons, others low
what is an ion?
an atom, or group of atoms, that has an electric charge
what determines the role of an ion?
its properties
give 4 ions that are important
sodium- Na+
phosphate
hydrogen
iron
importance of sodium ions
transporting glucose and amino acids
nerves
importance of phosphate ions
ATP,ADP,DNA,RNA
importance of hydrogen ions
lowers the PH
importance of iron ions
transports oxygen and is found in Haemoglobin
what is PH?
a measure of the hydrogen ion concentration of a solution
impact of hydrogen ions on PH
the higher the concentration of hydrogen ions, the lower the PH, the more acidic solution
by how much does the concentration of hydrogen ions increase between PH 7-6
10 times
how is PH calculated?
-log10[h+]
