Hydrophilic molecules that are to be released by cells are stored in membrane-bound structures called:_____

ahrayia [7]

Hydrophilic molecules that are to be released by cells are stored in membrane-bound structures called Secretory vesicles.

The head, which forms the outer and inner lining, is 'hydrophilic' (water-loving), while the tail facing the interior of the cell membrane is 'hydrophobic' (water-hating).

All lipid molecules in cell membranes are amphiphilic (or amphipathic). That is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“hydrophobic”) or non-polar end.

Cells contain membrane-bound structures called cellular organelles and more complex chemicals. Organelles are sometimes referred to as subunits within cells designed to perform specific functions.

Channel-forming proteins can be used to facilitate the transport of water and other hydrophilic molecules. These channels are often gated to regulate transport rates. In facilitated transport, a hydrophilic molecule binds to a 'carrier' protein. This is a form of passive transport.
