Final answer:
Raw proteins are synthesized on ribosomes and initially processed in the endoplasmic reticulum before being further modified and packaged in the Golgi apparatus. Proteins are not stored unmodified in any organelles including lysosomes, the Golgi apparatus, mitochondria, or vacuoles.
Step-by-step explanation:
In biological contexts, raw proteins synthesized on ribosomes are typically stored and modified in the endoplasmic reticulum (ER). After synthesis, proteins are sent to the Golgi apparatus where they are further organized, modified, packaged, and tagged for their final destinations. The Golgi then dispatches these proteins, either to other parts of the cell where they are needed or outside the cell via exocytosis. Newly synthesized enzymatic proteins may also be packaged into lysosomes by the Golgi apparatus. However, proteins are not stored in lysosomes, the Golgi apparatus, mitochondria, or vacuoles in a raw or unmodified state.
