| Term | Definition |
|---|---|
| Golgi apparatus | Synthesizes carbohydrate and combines it with protein. Packages product as globules of glycoprotein. |
| Lysosomes | Contains digestive enzymes that break down defective cell parts (autophagy). Known as cell's "digestive system". |
| Mitochondria | ATP synthesis, catabolism. Known as cell's "power plants". |
| Endoplasmic Reticulum (ER) | Ribosomes attached to rough ER synthesize polypeptides that enter rough ER then move on to smooth ER. Synthesizes integral membrane proteins and membrane lipids. Removes and stores calcium from cells interior. |
| Ribosomes | Site of protein synthesis, a cell's "protein factories". |
| Plasma Membrane | Boundary of the cell. houses protein molecules that perform different functions including transport mechanisms and identification. |
| Nucleus | Houses genetic code and dictates protein synthesis. |
| Nucleolus | Located within nucleus, site of formation of ribosome units. |
| Centrosome | The microtubule-organizing center. Centrioles assist in forming and organizing microtubules. |
| Microvilli | Tiny, fingerlike extensions that increase cells surface area absorption. |
| Cytoskeleton | Supporting framework of the cell. Functions in cell movement through molecular motors. Forms cell extensions. |
