Study Notes
Exocytosis
- Involves the transport of Golgi vesicles to export substances from the cell.
- Requires ATP for the process to occur.
- Examples include the release of neurotransmitters in nerve cells.
- Fungi and bacteria utilize exocytosis to secrete digestive enzymes.
- This process breaks down extracellular substances to absorb essential nutrients.
Endocytosis
- Comprises three primary types: phagocytosis, receptor-mediated endocytosis, and pinocytosis.
Phagocytosis
- A mechanism where cells engulf solid particles, forming large structures called phagosomes or vacuoles.
- Plays a crucial role in the immune response by allowing cells to consume pathogens.
Receptor-Mediated Endocytosis
- Occurs when specific hormones or viral particles bind to designated receptor proteins on the cell membrane.
- This binding facilitates the engulfment of the particles into the cell, enhancing selective uptake.
Pinocytosis
- A form of endocytosis characterized by the nonspecific uptake of extracellular fluid.
- Involves the formation of small vesicles known as pinocytic vesicles, allowing for the absorption of dissolved substances.
