Question

Arrange the pathway for a protein molecule from the site of its manufacture to its release in the target organelle.

• A. Rough ER
• B. Golgi apparatus
• C. Secretory vesicle
• D. Transport vesicle

Answer 1

• The rough endoplasmic reticulum has ribosomes attached to its surface. They synthesise proteins.
• These proteins are then sent to the Golgi apparatus in transport vesicles.
• The proteins are then modified in the Golgi apparatus.
• Then, the modified proteins are packaged in secretory vesicles and sent to their respective locations.
