Document Summary
How macromolecules make up cells and how cells make up tissues. How stem cells can be used for cell therapy. There are about 37. 2 trillion cells and 220 different cell types in the human body. Robert hooke - coined the term cells, built microscope, studied cork cells. Antoni van leuwenhoek - father of microbiology; first to observe bacterial and sperm cells, "animalcules" Cells on a microscope slide are incubated with a primary antibody that binds to an epitope on the protein. Low resolution (0. 2 um) highest resolution (2 nm) Pasteurization - heating liquids kills bacteria that cause spoilage. Originally used in beer and wine, now applied to milk. Diffusion: molecules in solution are in random and constant motion due to their kinetic energy (energy of motion) Move from areas of high concentration along a concentration gradient to areas of lower concentration and eventually become evenly distributed.
