Study Notes
Cellular Respiration
- Takes place in the mitochondria, the powerhouse of the cell where energy production occurs.
Storage Organelles
- Vacuoles store materials like water, nutrients, and waste.
- Vesicles also store and transport materials within the cell.
Protein Synthesis Organelles
- Ribosomes, endoplasmic reticulum (ER), Golgi apparatus, vesicles, and the nucleus work collectively to synthesize proteins.
Nucleus Function
- Produces the amino acid sequence for proteins via DNA processes such as transcription and translation.
Mitochondria as "Factory"
- Considered a factory due to its role in converting raw materials into usable cell products through cellular respiration.
Ribosomes Functionality
- Synthesize proteins and link amino acids.
- Exist as free ribosomes in the cytoplasm or bound to the rough ER.
Endoplasmic Reticulum (ER)
- Main function is to manufacture and transport materials within the cell.
Rough vs. Smooth ER
- Rough ER has ribosomes on its surface, responsible for protein synthesis.
- Smooth ER lacks ribosomes, involved in lipid synthesis and detoxification processes.
Lysosomes
- Organelles filled with enzymes that break down cellular materials and waste products.
- Responsible for digesting macromolecules and recycling cellular components.
Centrioles
- Structures involved in cell division, found only in animal cells.
