Plasma membrane
Function: Controls what passes through membrane
Phospholipid bilayer
Function: Give shape to the cell, form a scaffold
Spectrins
The cell takes in macromolecules by forming vesicles from the plasma membrane
Endocytosis
Double membrane, each membrane consists of a lipid bilayer
Nuclear membrane
Function: Backbone of cell membranes
Phospholipid
Function: Transport, support, communication, recognition, enzymatic, junctions
Proteins
Function: Form channels between cells (Gap junctions)
Junction proteins
When cells transport fluid into the cell using vesicles
Pinocytosis
Encloses the nucleus, separating it from the cytoplasm
Nuclear Envelope
Function: Energy storage, insulation, protection
Triglycerides
Function: Maintains proper fluidity of membrane
Cholestrol
Function: Line coated pits to facilitate receptor mediated endocytosis
Clathrins
When cells transport large particles and cells into the cell using vesicles
Phagocytosis
Liquid that fills the nucleus
Nucleoplasm
Functions: Useful for hormones and apart of cholesterol
Steroids
Identifies tissue types
Glycolipids
Function: Transmit messages from outside the cell to inside the cell
Cell Surface Receptors
When molecules attach to a receptor, and are then transported into the cell
Receptor-mediated endocytosis
Dense area in the nucleus is where rRNA are produced and ribosomes are assembled
Nucleolus
Function: Orange and yellow plant pigments play a role in photosynthesis
Carotenoids
Identifies cells as “our cells”. Ex: Hormones
Glycoproteins
Function: Transport water, important in kidneys and in certain bacteria
Aquaporins
The molecules in the Receptor-mediated endocytosis that specifically bind to a receptor
Ligands
Protein bind with DNA molecules
Histones
A linkage between fatty acids through condensation reaction
Ester linkage
