Inorganic Ions Flashcards
Where do inorganic ions occur
In the solution of the cytoplasm and body fluid of organisms
What are the main inorganic ions
Hydrogen, iron, sodium, phosphate ions
What do hydrogen ions determine
The pH of substances such as blood
How does the concentration of hydrogen ions affect pH
The higher the concentration of hydrogen ions, the lower the pH/more acidic it is
What are iron ions a component of
The haem group in haemoglobin
What is haemoglobin
A oxygen carrying molecule in red blood cells
What are sodium ions involved in
Co transport of glucose and amino acids
Action potentials in neurons
Affects water potential of cells/osmosis
What are phosphate ions a component of
Nucleotides (forming DNA/RNA)
ATP
They are the hydrophilic part of phospholipids
What do hydrogen ions cause enzymes to do? How does this affect the rate of reaction
The hydrogen ions can cause enzymes to denature if the pH is not optimal
This slows down the ROR
What do the iron ions in the haem group allow to happen
They allow oxygen to bind/associate for transport as part of oxyhemoglobin
What do phosphate ions do
Allow nucleotides to form phosphodiester bonds to make in DNA and RNA
Allowing energy release in ATP
It phosphorylates other compounds to make them more reactive
It is in the hydrophilic part of phospholipids allowing a bilayer to form
