Unformatted text preview: typical secretory protein; from the initial copying from DNA in the nucleus to the eventual secretion from the cell. 1. The RNA is exported from the nucleus. 2. The RNA message associates with a ribosome. 3. The signal sequence on the protein is recognized by the SRP. 4. Translation of the protein continues into the rough er. 5. The protein is sent to the Golgi apparatus. 6. The protein is folded and chemical modifications are made to the protein. 7. A transport vesicle fuses with the plasma membrane. 5. Acid hydrolases are only active at acidic pH because their purpose is to catalyze hydrolysis reactions in order to bring the cell to a pH of around 7. They are less effective in a solution with a pH >5. 6. Peroxisomes and vacuoles contain transporters for selected molecules....
