Co-transport-Goes against the concentration gradient
Electrogenic Pump-ions move down their electrochemical gradients
Endocytosis-food goes into the cell, those bigger then the pores
Exocytosis-food leaves the cells, those bigger then the pores

Active transport is diffision of nutrients through a partly-permeabale membrane. Its must require energy or go against the concentration gradient to be considered ACTIVE transport. Ex: 1. The Sodium-Potassium pump 2. The Proton pump (in plants, fungi, bacteria) 3. Bulk transportation (across the plasma membrane)

The three types are:
- endocytosis
- exocytosis
- protein pumps
Hope this helps!
