Inorganic ions (3.1.8) Flashcards
1
Q
where are inorganic ions found?
A
in solution in the cytoplasm and body fluids of organisms (some in high concentrations, others in very low concentrations)
2
Q
what is the main role of iron ions?
A
they are a component of haemoglobin so are involved in transporting oxygen
3
Q
what is the main role of phosphate ions?
A
they are components of DNA and ATP
4
Q
what is the main role of hydrogen ions?
A
they determine the pH of solutions and therefore the functioning of enzymes
5
Q
what is the main role of sodium ions?
A
they are involved in the co-transport of glucose and amino acids
6
Q
how do you calculate the pH of a solution using its hydrogen ion concentration?
A
pH = -log10[H+]
7
Q
how do you calculate the hydrogen ion concentration of a solution using its pH?
A
H+ = 10^-pH
