which type of cell would most likely have large quantities of endomembrane region 2 in this diagram?
cells that produce a high number of mitochondrial proteins
cells that produce a high number of secreted proteins
cells that produce a high number of lipids and steroids
cells that produce a high number of cytoplasmic proteins

Explanation:

Region 2 is the rough endoplasmic reticulum (RER). The RER is studded with ribosomes and is involved in the synthesis of proteins that are either secreted from the cell or inserted into the cell - membrane. Cells that produce a high number of secreted proteins require a large amount of RER for protein synthesis and initial folding and modification. Mitochondrial proteins are mainly synthesized in the cytoplasm but also have some components synthesized within the mitochondria. Lipids and steroids are synthesized in the smooth endoplasmic reticulum. Cytoplasmic proteins are synthesized on free - ribosomes in the cytoplasm, not primarily on the RER.

Answer:

cells that produce a high number of secreted proteins
