The cilia move in unison, creating a current that propels substances in one direction across the cell surface. For example, the ciliated cells that line the respiratory tract propel dust and bacteria trapped in mucus upward away from the lungs. The only example of a cell with a flagellum in the human body is the sperm cell. The organelles are suspended in the cytosol. It also contains proteins, lipids, carbohydrates, salts, and other solutes.
Many chemical reactions take place in the cytosol.
For example, enzymes in the cytosol begin the breakdown of nutrients to provide energy for cellular activities. You can think of the cytoskeleton as the bone and muscle of the cell. Cell inclusions are chemical substances that are produced by specific cells and stored in their cytosol. Glucose is then used by body cells for energy. FATS are cell inclusions found in fat cells.
