Question

Hair grows as the cells of your follicles secrete a protein called keratin into the space. The molecules push each other out of the follicle and onto your skin. The process of secreting the keratin involves the entire membrane, because the individual molecules are very large. Which form of transport is used by the cell?

Responses

A Endocytosis
B Facilitated Diffusion
C Exocytosis
D Passive Transport

Answer 1

C

Step-by-step explanation:

of the answers provided, Exocytosis is the only one which actively pushes molecules out of the cell. B and D are passive, which is not possible because it is a very large molecule. A means to take inside the cell. Therefore C is the only correct answer.
