Inorganic Ions Flashcards
1
Q
What do inorganic ions occur in?
A
Solutions like the cytoplasm and blood in varying concentrations
2
Q
What are the 6 inorganic ions?
A
Hydrogen ions, iron ions, sodium ions, phosphate ions, magnesium ions, calcium ions
3
Q
What is the role of the hydrogen ion?
A
- Lowers the pH of solutions and impacts enzyme and haemoglobin functions
- Role in chemiosmosis
4
Q
What is the symbols of the hydrogen ion?
A
H+
5
Q
What is the role of the iron ion?
A
- Found in the haem group of haemoglobin for transportation of oxygen around the body
- Haemoglobin is a large protein made up of 4 different peptides and iron in the centre
- Iron ion binds to the oxygen in the haemoglobin
- Fe2+ temporarily becomes Fe3+ when oxygen is bonded until released
6
Q
What is the symbol of iron ions?
A
Fe2+
7
Q
What is the role of sodium ions?
A
- Involved in co transport of glucose and amino acids
- Sodium is transported alongside glucose and amino acids across a cell membrane
- Role in generating action potentials
8
Q
What is the symbol of sodium ions?
A
Na+
9
Q
What is the role of the phosphate ions?
A
- Component of DNA
- Synthesis of ATP and production of phospholipids
10
Q
What is the symbol for phosphate ions?
A
PO (3- at top) (4 at bottom)
11
Q
What is the role of magnesium ions?
A
- Component of chlorophyll
- Needed for photosynthesis
12
Q
What is the symbol for magnesium ions?
A
Mg2+
13
Q
What is the role of calcium ions?
A
- Involved in ossification of the bones and teeth
- Involved in synaptic transmission
14
Q
What is the symbol for calcium ions?
A
Ca2+
15
Q
What is ossification?
A
The hardening of teeth and bones
