Exploring Passive and Active Transport Mechanisms

The video tutorial by Jonas Bobby George covers the differences between passive and active transport. It explains passive transport methods like diffusion, osmosis, and facilitated diffusion, which do not require energy. Active transport methods such as endocytosis, exocytosis, and protein pumps require energy to move materials against the concentration gradient. The video also includes a fictional story where heroes stop Dr. Drain's evil plan to misuse active transport. The tutorial concludes with a summary of the key differences between passive and active transport.

What are the three types of passive transport?

• Diffusion, facilitated diffusion, osmosis

• Diffusion, endocytosis, exocytosis

• Endocytosis, exocytosis, protein pumps

• Active transport, passive transport, osmosis
