membranous

ZIP7 is also the only zinc transporter found in the endoplasmic reticulum, a membranous structure where a cell makes proteins destined for the outer membrane of the cell or for secretion out of the cell.

The organelles consist of stacks of membranous sacs that process and package proteins so that they can be transported to other parts of the cell or excreted from the cell.

It then must move to another membranous network in the cell called the endoplasmic reticulum.

The tiny baby octopuses—each about the size of a nickel—emerged from soft, membranous eggs, clutched in their mothers’ protective embrace.

Between the echoing blasts of fireworks, I discerned a flapping sound like the unfurling of membranous wings.
