JudyThe endoplasmic reticulum (ER) and the Golgi apparatus are the main membranes involved in packing proteins for export in eukaryotic cells. Proteins are first synthesized in the ER and then transported to the Golgi apparatus for further processing, sorting, and packaging into vesicles for export outside the cell.

What is the organelle that prepares proteins for export and synthesizes steroids?
The organelle responsible for preparing proteins for export and synthesizing steroids is the endoplasmic reticulum. It has two forms, rough ER, which is studded with ribosomes for protein synthesis, and smooth ER, which is involved in lipid and steroid synthesis.
What repackages proteins into forms the cell can use and expel or keep stored?
The Golgi apparatus is responsible for repackaging proteins into forms the cell can use, either by modifying them or adding additional molecules. It can also sort proteins for export out of the cell, storage within the cell, or incorporation into cell membranes.
What flatten membranes that package cellular substances for export?
Golgi Bodies :)
Flattened membranes that package cellular substances for export?
Golgi bodies
How does the function of free ribosomes differ from the function of ribosomes attached to other organelles?
Free ribosomes synthesize proteins that will function within the cytoplasm of the cell, whereas ribosomes attached to other organelles like the endoplasmic reticulum (ER) synthesize proteins that are destined for secretion, insertion into membranes, or for use in other organelles. The ribosomes attached to the ER are involved in producing proteins for export or for insertion into the cell membrane.
