, Compartmentalization - ✔✔Distinct sub cellular compartments and
organizations that allow chemical rxns that require different environments
to occur simultaneously
Cell Theory - ✔✔1. All organisms consist of one or more cells.
2. Cells are the smallest units characteristic of life.
3. All cells arise from pre-existing cells
Components of plasma membrane - ✔✔Complex lipid bilayer, phosphate
and carb components, and proteins
Plasma membrane function - ✔✔1. Maintain physical integrity of the cell.
2. Facilitate the entry of nutrients, ions, and other molecules
Integrins - ✔✔Transmembrane proteins that mediate a cells adhesion to
other cells or the ECM.
Integrate info between inside and outside the cell
Integrin structure - ✔✔Heterodimeric - made of two unlike subunits (alpha
and beta) that are large on the outside of cell and small on the inside of cell
and that can help determine it's shape and mobility
Cytoskeleton function - ✔✔1. Gives cell structure, organization, and
shape/stability.
2. important role in cell division & molecule transport
