Inorganic Ions Flashcards
Where are inorganic ions found in the body/cells?
In solution in fluids or in cell cytoplasms.
Give 3 examples of molecules where phosphates are found.
Phospholipids, nucleotides, ATP
What do hydrogen ions do?
Maintain pH levels in the body.
If pH concentration is incorrect, how does this affect enzymes?
Incorrect pH causes enzymes to denature.
What part of red blood cells do Fe2+ form a part of?
They form part of the haem group in haemoglobin.
Describe the use of Fe2+ in red blood cells.
What happens to the charge on the Fe ion?
Oxygen binds to the Fe 2+ ion, so oxygen is carried within the red blood cells.
This temporarily forms Fe 3+.
Which cellular process are Na+ ions used in?
Co transport of amino acids across cell membranes.
How are Na ions used in nerves/muscles?
Allow for nerve impulses to be sent
Allow for muscle contraction
