Cells (5.1, 5.3) A cell can be compared to a room in a house. Some examples of cell types: red blood cells; transport oxygen, contain no nucleus whiite blood cells; fight infection Microscopy Mammalian cells can be viewed through microscopes due to their typical size of 10 micrometers. Conventional microscopy is suitable for this application but fluorescence will add clarity. To view organelles, electron microscopy must be used. Resolution of a microscope depends on (wave)length. *Note slide

Structure of a Protein defines its function. Proteins do the work; involved in structure, movement, enzymes, transport, regulation of cells. Example: Kinesin protein transporting Vesicles through the skin (part of cytoskeleton). These proteins can 'walk' over the microtubules (by detachment and reattachment), transporting them from the surface of the cell toward the nucleus. Proteins are polymers; long chains of amino acids. Key elements: Carbon, amino group, carboxylic acid group. (Note chemica
