Question

In order for a milk protein to be secreted, it must be moved between organelles

A. in spheres of lipid bilayer called vesicles.
B. by release into the cytoplasm.
C. All answers are correct.
D. attached to transporter proteins.
E. by the fusion of organelles with each other.

Answer 1

Milk proteins are moved between organelles using vesicles, which bud from the trans face of the Golgi apparatus. The vesicles can either deposit their contents into other parts of the cell or fuse with the plasma membrane to release their contents outside the cell.

Step-by-step explanation:

For a milk protein to be secreted, it must be moved between organelles in spheres of lipid bilayer called vesicles. These vesicles bud from the trans face of the Golgi apparatus and can either deposit their contents into other parts of the cell or fuse with the plasma membrane to release their contents outside the cell. This process allows for the transportation and secretion of proteins throughout the cell and to the extracellular fluid.
