Cell Transport
- Passive
- Small molecules that don´t need a
lot of energy. Depend in the
concentration gradient
- Difussion
- Free pass throught de cell
membrane, from inside to outside. In
favor of concentration gradient
- Going from + to -
- Simple
- Is the most simple
- Facilitated
- Requieres proteins that
can open their way to the
membrane
- Going from + to -
- Osmosis
- Is the pass of water. In favor
of concentration gradient
- Going from + to -
- Active
- Needs more energy. Its purpose is
to go against gradient. Transport
could be in and out
- Going from - to +
- Active
- Big molecules or cells thats don´t
depend to the concentration gradient.
Its functions is to digest bacteries and
pull molecules
- Endocytosis
- Goes in the cell
- Phagocytosis
- Molecules or cells (food)
- Pinocytosis
- Water and liquids
- Exocytosis
- Goes out the cell
