Chapter 7: Membrane Structure and Function

Chapter 7: Membrane Structure and Function. The Cell Membrane. It is a fluid mixture of proteins, lipids and some carbohydrates. It has 2 layers which are composed of phospholipids. The Phospholipid Bilayer. Both sides of the bilayer are aqueous.

Plasma Membrane Structure and Function

Plasma Membrane Structure and Function Separates the internal environment of the cell from its surroundings. Regulates what materials enter and leave a cell Made of 2 layers of phospholipids ( phospholipid bilayer ) with proteins embedded throughout.

Biology of the T lymphocyte

Biology of the T lymphocyte. Nature of T cell - overview. T cells have a receptor for Ag on surface (TCR) which share similarities for Ig receptor on B cells; but differs: Ig can interact with Ag directly (even in solution), yet TCR recognize Ag when bound to MHC molecules.

Membranes

Membranes. Cell membrane = Plasmalemma = Plasma membrane Surrounds cells and most organelles Forms a network of passages. Mitochondria, chloroplasts, and the nucleus all have a double membrane. Functions of plasmalemma. Keep cell contents together and separate from other cells

Cell Membrane

Cell Membrane. Who am I?. I am a protein molecule that is permanently attached or firmly anchored in the plasma membrane. I also serve as transport proteins, chemical receptors, and regulators for cell to cell recognition. Integral proteins.

Invertebrate Characteristics

Invertebrate Characteristics. Symmetry- Bilarteral or Radial Segmentation- repeating similar units Exoskeleton-rigid outer covering which protects the soft tissue of many animals. Gas exchange (respiration) occurs through body cavities, but some have gills.
