Catabolic: large to small molecules

Anabolic: small to large molecules


-Small molecules joined to make big ones

-Water molecule released

-Covalent bond formed

-Monomers join to make polymers

-A weak interaction that can occur between molecules that contain a slightly
negatively charged atom and slightly positively charged…

temperate such as H(2)S but due to the amount of hydrogen bonds H(2)O remains a

If you heat water, the temperature of the water rises. Temperature relates to
the amount of kinetic energy that the water molecules have.
As heat energy is added to the water, a lot…

When liquid sweat lies on the surface of the skin, the water in the sweat
absorbs heat energy from the body as it evaporates. The heat needed to do
this is called latent heat of evaporation. It is our major cooling mechanism.
It also helps to cool plant leaves in…

Placing cells in a concentrated salt or sugar solution with a water potential lower than the
cell contents means there is a water potential gradient form inside to outside the cell.
Therefore water molecules move out via osmosis. This makes the cell shrink and in animals
the cell membrane `wrinkles…
