Found an amazing vid that shows every bit of happenings inside a cell with bright and vivid graphic presentation.

Notes:
Cell – the smallest unit of life. It takes up useful molecules and gets rid of waste molecules. It breaks down larger molecules to produce usable energy in the form of ATP molecules, where energy was stored, to synthesize other larger molecules. Big molecules are CONSTANTLY being breaking down into small molecules and the pieces used to make big molecules again, a process called ‘turnover’.

Selectin – any of a family of sugar-binding lectins that are found on the surface of cells (as endothelial cells and white blood cells) and that promote their adhesion to other cells and mediate their migration to sites of inflammation.

Leukocytes – white blood cell

Chemokine – any of a group of chemotactic cytokines that are produced by various cells (as at sites of inflammation), that are thought to provide directional cues for the movement of white blood cells (as T cells, monocytes, and neutrophils), and that include some playing a role in HIV infection because the cell surface receptors to which they bind are also used by specific strains of HIV for entry into cells.

Proteoglycan – any of a class of glycoproteins of high molecular weight that are found in the extracellular matrix of connective tissue, are made up mostly of carbohydrate consisting of various polysaccharide side chains linked to a protein, and resemble polysaccharides rather than proteins in their properties.

2 classes of receptors –
Ligand-gated ion channel
G protein-coupled receptor

Mitochondria – an organelle which break down nutrients such as glucose and provide the cell with energy to perform its function.

Membrane – defines the boundary of the cell and consists of a double layer of fatlike lipid molecules. Embedded in the membrane are a variety of protein molecules that have special functions.

Microtubule – a long strand of bundles of protein filaments arranged around a hollow core; part of the cytoskeleton and involved in transporting substances from place to place within a cell.

G-protein – a protein coupled to a metabotropic receptor. When a molecule of the neurotransmitter binds with the receptor, the receptor activates a G protein situated inside the membrane next to the receptor.
