Study Notes
- Cells maintain homeostasis to keep internal conditions stable despite changes in the environment, allowing them to function optimally.
- Homeostasis involves maintaining a balance of water, salt, sugar concentrations, and pH levels within cells to support chemical reactions necessary for survival.
- The cell membrane plays a crucial role in maintaining homeostasis by regulating the movement of materials into and out of the cell.
- Osmosis is a passive transport process where water moves from high to low concentration to help cells maintain the right amount of water.
- Active transport, facilitated by proteins in the cell membrane, helps maintain optimal levels of ions like potassium and sodium inside and outside the cell to support homeostasis.
