Final answer:
Toxic APP fragments are generated by the Golgi apparatus in the cell. The Golgi apparatus receives proteins and other products from the rough endoplasmic reticulum (ER) and organizes, modifies, packages, and tags them.
Step-by-step explanation:
Toxic APP fragments are generated by the Golgi apparatus. The Golgi apparatus receives proteins and other products from the rough endoplasmic reticulum (ER), and organizes, modifies, packages, and tags them. Some of these products, including toxic APP fragments, are transported to other areas of the cell or exported from the cell through exocytosis.
