Question

Lipophobic molecules that are to be released by cells are stored in membrane-bound structures called ________.

A) secretory vesicles
B) inclusions
C) the Golgi apparatus
D) excretory vesicles
E) the endoplasmic reticulum

Answer 1

Lipophobic molecules meant for release from the cell are stored in secretory vesicles until they are transported out of the cell through exocytosis.

Step-by-step explanation:

Lipophobic molecules that are to be released by cells are typically stored in membrane-bound structures known as secretory vesicles. Exocytosis is the process where these secretory vesicles release their contents outside the cell. This process occurs in a few steps, starting with the synthesis of materials in the endoplasmic reticulum (ER), then the modification and sorting of these products in the Golgi apparatus, and finally the packing of these materials into vesicles. Among the options provided, the correct answer is A) secretory vesicles.
