Organelles Functions Flashcards
Serves as a scaffold that helps determine the cell’s shape and organize the cellular component
Cytoskeleton
Aids Movement of organelles within the cell, of chromosomes during cell division and of whole cells such as phagocytes
Cytoskeleton
The most famous moving cells are
- Sperm
- Cancer Cells
Types of Filaments (3 types)
arranged according to size
- Microfilament
- Intermediate Filament
- Microtubules
The pericentriolar matrix of the centrosome contains tubulins that build microtubules in nondividing cells.
Centrosome
The pericentriolar matrix of the centrosome forms the mitotic spindle during cell division
Centrosome
Non dividing cells which become dividing cells
Sperm and Ovules become zygote
moves fluids along cell’s surface
Cilia
Moves entire cell
flagellum
Synthesizes protein destined for insertion in the plasma membrane or secretion from the cell
Ribosomes associated with endoplasmic reticulum
Synthesizes proteins used in the cytosol
Free Ribosomes
babies need
Calcium and Protein
synthesizes glycoproteins and phospholipids that are transferred into cellular organelles, inserted into the plasma membrane or secreted during exocytosis
Rough Endoplasmic Reticulum
Synthesizes fatty acids and steroids, such as estrogens and testosterone
Smooth Endoplasmic Reticulum
inactivates or detoxifies drugs and other potentially harmful substances
Smooth Endoplasmic Reticulum
Removes phosphate group from glucose-6-phosphate
Smooth Endoplasmic Reticulum
Stores and releases calcium ions that trigger contraction in muscle cells
Smooth Endoplasmic Reticulum
Modifies, sorts, packages and transports proteins received from the rough ER.
Golgi Complex
Forms secretory vesicles that discharge processed proteins via exocytosis into extracellular fluid
Golgi Complex
Forms membrane vesicles that ferry new molecules to the plasma membrane
Golgi Complex
Forms transport vesicles that carry molecules to other organelles, such as lysosomes
