Inorganic ions

Question 1

Function + charge of magnesium ion

Answer 1

Mg 2+ → component of chlorophyll needed forphotosynthesis + healthy growth → lack of = chlorosis = yellow leaves + stunted growth
Mammals → proper bone development

Question 2

Function + charge of iron ions

Answer 2

Fe 2+ → c omponent of the protein haemoglobin needed to absorb and transport oxygen around body for respiration → lack of= not enough red blood cells made= anaemia with fatigue, paleness, breathlessness and dizziness

Question 3

Function + charge of calcium ions

Answer 3

Ca2+ → strengthening tissue, teeth and bones in mammals + cell walls in plants

Question 4

Function + charge of phosphate ions

Answer 4

(PO4) 3- → makes nucleotides which make DNA, RNA, ATP and phospholipids → overall component of nucleic acids

Question 5

Function of phospholipids

Answer 5

Part of lipid making up cell membrane
