Document Summary

Cytoplasm: cellular material between the plasma membrane and the nucleus (where most cellular activity happens) Cytosol: viscous, semitransparent fluid where other cytoplasmic elements are suspended. Inclusions: chemical substances that may or may not be present (ex. lipid droplets in fat cells) Organelles: metabolic machinery of the cell (each with a specific function ex. synthesise proteins) 3. 7 cytoplasmic organelles each perform a specialized task. Mitochondria are the power plants of the cells, providing most of the atp supply. Busier cells require hundreds of mitochondria, while less demanded cells only require a few. It is enclosed with the outer and inner membranes (the inner membrane fold inwards) Function: break down food fuels (glucose, etc. ) to h2o and co2. Some of their energy released is used to attach phosphate groups to adp to make atp. There are free ribosomes (fr), which float freely in the cytosol; and membrane-bound ribosomes (mr), which are attached to membranes.
