What is cell homeostasis? |
Maintaining a near constant balance between the inside of the cell and the external environment. Cell membrane responsible for maintaining this balance. Involves transporting molecules across the cell membrane. |
|
|
What is passive transport? |
Transport across the cell membrane that does not require ATP energy. |
|
|
What types of transport are passive? |
Diffusion, osmosis, facilitates diffusion. |
|
|
What is diffusion? |
Process of solute molecules moving from high concentration areas to low concentration areas across concentration gradient of the cell. |
|
|
What is Brownian motion? |
Molecules constantly moving because of kinetic energy. They will bump into one another and spread out. |
|
|
What is osmosis? |
The diffusion of water from high to low concentrations. Solute concentration of a solution drives the movement of water. |
|
|
What is a hypotonic solution? |
When the concentration of the solute is low compared to another solution. Can cause cytolysis which causes cells to become swollen and burst. |
