Question

Compare and contrast passive transport with active transport. Please have them in bulletpoints. Don't need to have full sentences.

Answer 1

both

• both are systems that move water nutrients into cells and remove waste

passive

• movement of molecules DOWN the concentration gradient ( no cellular energy needed)
• maintains an equal balance between water, gases, nutrients,
• etc...

active transport

• uses ATP to pump molecules UP the concentration gradient ( requires cellular energy)
• moves molecules through the cell membrane against the concentration gradient
• disrupts the equal balance made by diffusion
