Summary
Light and Transmission Electron Microscopy
CELL AND CYTOPLASM
Cells maintain proper homeostasis of the body
Structural features are common to all cells
CELL MEMBRANE
Consists of phospholipid bilayer and integral (transmembrane) membrane
proteins
Peripheral membrane proteins located on external and internal cell surfaces
Peripheral proteins anchored to microfilaments of cytoskeleton
Transmembrane proteins are located within lipid bilayer of the cell
membrane
Transmembrane proteins transport molecules across lipid bilayer
