2.2.1 Biological Molecules Water Flashcards
What makes water a polar molecule?
Positively charged hydrogen pole
Negatively charged oxygen pole
What metabolic reactions use/produce water?
Condensation produce water
Hydrolysis use up water
What makes water a good solvent?
It is polar
Meaning that it attracts both positively and negatively charged ions
What does having a high heat specific capacity mean?
A lot of heat energy is required to change the temperature of the substance
What causes water to have a high heat specific capacity?
Many hydrogen bonds between water molecules
What does water having a large latent heat of vaporisation mean?
When water evaporates it a cooling effect is produced, minimising water loss
What causes water to have a high level of cohesion?
Hydrogen bonds between water molecules
What occurs due to waters low density?
Ice floats providing insulation for organisms
