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.
Test your knowledge about the functions and importance of cell organelles in human biology. Explore the roles of cells in producing energy, cleaning up waste, and synthesizing proteins.
