1
Q
Properties of water important in cytoplasm
A
polar molecule - universal solvent
Universal solvent - reactions occur faster in solution
reactive - hydrolysis/condensation reactions can occur
2
Q
Polar definition
A
Uneven spread of electronic charge
3
Q
Why is a polar bond polar?
A
asymetrical shape
4
Q
why is water a good sign towards life? (use properties of water)
A
Ice less dense than water - floats on water - life can thrive below the ice cap
increased surface tension - small organisms populate surface
High specific heat capacity - absorb a lot of heat energy without increasing in temperature, - chance of aquatic life
