Study Notes
Centrioles
- Non-membranous organelles
- Composed of highly organized microtubules
- Appear as two dark bodies near the nucleus when stained with iron hematoxylin
Cytoplasmic Inclusions
- Temporary, nonliving, and nonessential metabolically inactive materials in the cytoplasm
- Stored food
- Carbohydrates
- Stored in the liver and muscle as glycogen
- Appear as light areas formed of nucleolar sap
- Carbohydrates
Cell Renewal
- Most mature specialized cells are not in the active cell cycle (mitosis-interphase-mitosis)
- Energy is stored as ATP molecules through oxidative phosphorylation
Rough Endoplasmic Reticulum (rER)
- Membranous organelle responsible for protein synthesis
- Present mainly in protein-secreting cells
- Hydrolytic enzymes are synthesized in the rER, transferred to the Golgi apparatus, and released as primary lysosomes
- Cannot be seen with light microscopy, but the acid phosphatase enzyme inside the lysosome can be detected by histochemical reactions
