Study Notes
Cell Structure and Function
- The cell membrane, also known as the plasma membrane, acts as a semi-permeable barrier that regulates the movement of materials in and out of the cell.
Cellular Respiration
- The mitochondria is the organelle responsible for generating ATP energy through cellular respiration.
Vesicles and Vacuoles
- Vacuoles are membrane-bound organelles that store and transport materials, helping to maintain cellular homeostasis and recycle cellular waste.
- Vesicles are small, membrane-bound sacs that facilitate the transportation and storage of molecules within the cell.
Protein Synthesis
- The main job of cells is to synthesize proteins, which are essential for various cellular functions, growth, and maintenance.
Lysosomes
- Lysosomes are membrane-bound organelles that contain digestive enzymes, breaking down and recycling cellular waste and foreign substances, maintaining cellular health.
