Question

What types of materials are expelled from cells during exocytosis?

Answer 1

Answer:

Large molecules such as hormones

Explanation:

The other options either have channels within the membrane to move through (water has aquaporins, ions like potassium have their own channels) or can diffuse directly through the membrane (CO2). Protein hormones cannot move through the plasma membrane, nor can they diffuse through it. Hope this helps!
