Energy is used[Low] [High]
This means it goes up or against a concentration gradient

Protein PumpsProtein Pumps: proteins use energy to pull or pump
materials into or out of the cell to stockpile or store substances the cell needs

• When a particle is engulfed into the cell.• 2 types
1. Phagocytosis: When a cell wraps part of its membrane arounda large particle forming a “pocket” or vesicle
2. Pinocytosis: The same process, but with smaller particles or liquids
Endocytosis
