Cell and Sub-Cellular Organelles - Lysosomes

Vocabulary flashcards based on lecture notes about Lysosomes and their functions within cells.

Lysosomes

Single membranous, spherical vesicles containing digestive or hydrolytic enzymes.

Digestive or Hydrolytic Enzymes

Enzymes that breakdown major macromolecules of the cell.

Endocytosis

The cell membrane falls in creating a vacuole or pouch around external contents bringing those contents into the cell.

Autophagy

The process by which unwanted structures within the cell are engulfed and digested within the lysosomes.

Autophagosomes

Lysosomes that digest cell's own organelles.

Autolysis

Programmed cell death in which lysosomes burst and their enzyme contents are dispersed throughout the cytoplasm, disintegrating the cell.

Primary Lysosomes

Newly formed lysosomes, prior to the start of their digestive functions.

Phagosome

A vesicle containing a foreign particle brought into the cell through endocytosis.
