AP Bio Cell Transport

Sodium/potassium pump moving 3 Na⁺ out and 2 K⁺ into neuron (nervous cell).

Identify type of transport used.

• Active

• Facilitated

• Simple

Describe the process of receptor-mediated endocytosis

Evaluate responses using AI:

OFF

Answer explanation

A ligand (signaling molecule) binds to a receptor protein. After signal transduction, the membrane undergoes invagination to create a “pit” that forms the vesicle.
