Study Notes
Obesity and Health Fads
- A person is considered obese when they have over 30% body fat.
Functions of Cell Organelles
- Cell Wall: Provides strength and support.
- Cell Membrane: Regulates what enters and exits the cell.
- Nucleus: Contains the genetic material (DNA).
- Nucleolus: (Part of the nucleus) involved in ribosome synthesis.
- Ribosome: Involved in protein synthesis.
- Smooth Endoplasmic Reticulum (SER): Involved in lipid synthesis and detoxification.
- Rough Endoplasmic Reticulum (RER): Involved in protein synthesis and modification.
- Mitochondria: Produces chemical energy (ATP).
- Golgi Apparatus: Modifies, sorts, and packages proteins.
- Vacuole: Stores materials.
- Central Vacuole: A large vacuole found in plant cells.
- Lysosome: Contains enzymes that break down materials.
- Chloroplast: Captures sunlight for energy.
- Cytoskeleton: Helps the cell maintain its shape.
- Cytoplasm: The jelly-like substance that fills the cell.
