Study Notes
The Cell
- Cells have many forms and shapes.
- The eukaryotic cell has a cell membrane, nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, centriole, and mitochondria.
Ribosomes
- Ribosomes are composed of a large (60S) and small (40S) subunit.
- Ribosomes contain rRNA to stabilize structure.
- Ribosomes are produced and assembled in the nucleolus.
- Ribosomes are responsible for protein synthesis.
Golgi Apparatus
- The Golgi apparatus is responsible for polysaccharide synthesis, modifying secretory products, sorting secretory products, packaging secretory products, concentrating secretory products, and storing secretory products.
Endoplasmic Reticulum
- The endoplasmic reticulum (ER) is responsible for synthesizing, packing, and processing molecules.
- The ER has two forms: rough ER (RER) and smooth ER (SER).
-
Rough ER (RER)
- Sequesters proteins from the cytoplasm.
- Processes secretory, integral membrane, and lysosomal proteins.
- Participates in core glycosylation.
-
Smooth ER (SER)
- Participates in lipid metabolism, steroid hormone synthesis, gluconeogenesis, detoxification.
Vesicles
- Granules: Vesicles destined for exocytosis, abundant in specialized secretory cells.
- Lysosomes: Contain hydrolytic enzymes with a pH of 5, degrade material.
- Peroxysomes: Participate in hydrogen peroxide metabolism, assist in fatty acid oxidation.
Mitochondria
- The mitochondria is called the "powerhouse of the cell."
- Mitochondria synthesize their own DNA and some proteins.
- Mitochondria grow and reproduce.
- Mitochondria can move rapidly and change shape.
- Mitochondria have their own DNA (mtDNA).
- mtDNA is maternally inherited.
- Mitochondria have an outer membrane permeable to molecules.
