Which organelle digests materials?

• Lysosome

• Nucleus

• Golgi Apparatus

• Mitochondria

Which organelle processes and transports molecules?

• Golgi apparatus

• Nucleus

• Lysosome

• Mitochondria

Vesicles:

• Transport materials

• Come from the Golgi Apparatus

• Are formed by SNAREs

• Have lipid membranes

When phospholipids are placed in water

• A lipid bilayer will form spontaneously

• Energy must be added to form a lipid bilayer

In exocytosis:

• Molecules leave the cell

• Molecules enter the cell

In regulated secretion, cells release molecules:

• At a regular rate

• In response to signals

In constitutive secretion, cells release molecules:

• At a regular rate

• In response to signals

In endocytosis:

• Molecules leave the cell

• Molecules enter the cell

In phagocytosis:

• Large particles enter the cell

• Small particles enter the cell

In pinocytosis:

• Large particles enter the cell

• Small particles enter the cell
