Questions and Answers

What are three examples of exocytosis?

Transport of Golgi vesicles to export substances out of cell, transport of neurotransmitters, secreting digestive enzymes.

What are three examples of endocytosis?

Phagocytosis, receptor-mediated endocytosis, pinocytosis.

What is phagocytosis?

Cell engulfing solids to form large phagosomes or vacuoles.

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.
