Study Notes
Golgi Apparatus
- Stacks of flattened sacs
- Responsible for packaging and secreting proteins
- Receives proteins from the endoplasmic reticulum (ER)
Mitochondria
- Has two membranes: an outer membrane and an inner membrane
- The outer membrane is continuous and encloses a central space
- The inner membrane forms folds called cristae that project into the central space
Lysosomes
- Spherical sacs surrounded by a single membrane
- Contain digestive enzymes
- Responsible for intracellular digestion
