Flashcards do conjunto (18)
- 1Cytoplasm DefCytoplasm is the aqueous medium in which various organelles are suspended.
- 2Nucleus defNucleus contains blueprint for cell structure and function in the form of DNA
- 3Cell Membrane defPlasma membrane consists primarily of phospholipid molecules. Plasma membrane also includes proteins and carbohydrates
- 4Proteins in a cell membrane ex.ATPase, ion channels, hormone receptors
- 5Glycoproteins defOligosaccharides bound to membrane proteins
- 6Glycolipids defOligosaccharides bound to membrane lipids
- 7Endocytosis defbulk uptake of material through the plasma membrane
- 8Fluid-Phase pinocytosis defNon-specific endocytosis of fluid and molecules around cell. Enters cell by invagination and pinching off of cell membrane
- 9Fluid-Phase pinocytosis ex.macrophages, leukocytes, endothelial cells, microvilli of the intestine, kidney cells, epithelial cells of the intestine
- 10Receptor-mediated Endocytosis defSpecific endocytosis by target molecule binding to receptor. Invaginates and pinches off
- 11Receptor-mediated endocytosis ex.Cells internalize proteins, some hormones, and growth factors by this process. Phagocytosis by macrophage and neutrophil
- 12Exocytosis defbulk removal of material through the plasma membrane by vesicle binding to plasma membrane and releasing contents
- 13Exocytosis ex.Secretory products (digestive enzymes, antibodies)
- 14Secretion def.release of useful products
- 15Excretion defRelease of waste products
- 16Chromatin def.DNA and histones
- 17Euchromatin def.Chromatin is less coiled. Present in active cells
- 18HeterochromatinChromatin is more coiled. Present in less active cells.
