Passive transport doesn't require energy (ATP), active transport does require energy.
Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
They both allow the cell to maintain homeostasis by maintaining an equilibrium of subtances in and out of the cell.
They both involve moving material across or through the plasma membrane.
Both involve ion movement. Both use ion channels to move ions across the cell membrane, in or out of the cell.
Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP. Active Transport uses an ion pump (or Sodium/Potassium pump) to move 3 sodium ions out of the cell and 2 potassium ions in to the cell through the energy of 1 ATP molecule.
- Passive transport moves along the concentration gradient (High concentration --> low concentration) ; Active transport moves against the concentration gradient ( low concentration --> high concentration )
- ATP is required in active transport ; no cellular energy is required for passive transport
- Sodium Potassium pump/ proton pump = examples of active transport ; Diffusion / osmosis = examples of passive transport
- Involve the transport of a substance across a membrane
- Passive transport and Active transport are important to the proper functioning of a cell
One is both are active and two is both contain nucleaus.
One is passive which means passes where it needs to go. another is active means in movement. one more is that one is good for the body and one is not.
