Water, ATP and Inorganic Ions
Water
Properties
-
-
It has a high specific heat capacity meaning it takes a larger amount of energy too heat 1g of water by 1*C.
It has a high latent heat of vaporization, meaning it takes a lot of heat to break the hydrogen bonds.
-
-
-
ATP
This is made up of three phosphate groups, adenine and also pentose sugar
Once made, it diffuses to the part of the cell that needs energy.

Inorganic Ions
Iron Ions in Haemoglobin
-
When oxygen is bound the Iron ion gains a charge of +3 instead of +2, until the oxygen is released.
Hydrogen Ions
The more H+ ions present the lower the pH, as H+ ions are acidic.
Sodium Ions
A molecule of glucose or an amino acid can be transported into a cell, across the cell-surface membranes, alongside sodium ions.
-
Phosphate Ions
When a phosphate ion is attached to another molecule, it's known as a phosphate group.
