Inorganic Ions

Question 1

What are the six inorganic ions?

Answer 1

1. Hydrogen ions
2. Iron ions
3. Sodium ions
4. Phosphate ions
5. Calcium ions
6. Magnesium ions

Question 2

What do hydrogen ions do?

Answer 2

• lower pH of solutions and impact enzyme function and haemoglobin function
• role in chemiosmosis

Question 3

What do iron ions do?

Answer 3

• component of haemoglobin in transport of oxygen
• Fe2+ temporarily become Fe3+ when oxygen is bonded until released

Question 4

What do sodium ions do?

Answer 4

• involved in co transport of glucose and amino acids in absorption alongside sodium ions
• role in generating action potentials

Question 5

What do phosphate ions do?

Answer 5

• component of DNA (forms phosphodiester bonds with deoxyribose) and ATP (makes ADP more reactive)
• synthesis of ATP and production of phospholipids in DNA

Question 6

What does calcium ions do?

Answer 6

• involved in hardening/strengthening of bones and teeth
• synaptic transmission , connecting neurones

Question 7

What do magnesium ions do?

Answer 7

• component of chlorophyll required for photosynthesis
