FarazKlinglerCells
Organelles
-
Mitochondria are site of ATP synthesis, powerhouse of cell
Golgi apparatus packages, modifies and segregates proteins from the cell. Inclusion in lysosomes and into plasma membrane.
Peroxisomes are the enzymes that detoxify a number of toxic substances. Most important enzyme catalase.
-
-
-
Intermediate filaments the stable cytoskeletal elements, resist tension and forces actin on cells
-
-
Centrioles organize a microtuble network during mitosis to form the spindle and asters form the bases of cilia and flagella
Endocytosis
Receptor mediated endocytosis selected particles that have the right fit come in and bin with substance
-
Pinocytosis a vescicle is formed in plasma membrane. Bits are taken in and pinched off and brought to a new cell.
The Cell
Nucleus: Surrounded by nuclear envelope, fluid nucleoplasm, nucleolus and chromatin. The control center of the cell. provides protein synthesis and transmits genetic information.
-
Plasma Membrane: made of phospholipid bilayer and proteinsto allow things to pass through. Receptors to transmit infromation from outside to inside of the cell.

-
a mechanism by which substances move from the cytoplasm to the outside of the cell. Goblet cells go to atypical surface and leave.
