ATP, Water, and inorganic ions Flashcards
1
Q
Six properties of water
A
- Metabolite in many metabolic reactions e.g. hydrolysis
- Solvent where reactions occur e.g. in the cytoplasm
- Relatively high heat capacity
- Large latent heat of vaporisation
- Strong cohesion between water molecules
- Ice is less dense than water
