Homeostasis

Front

What is Homeostasis?

Back

The process by which living organisms regulate their internal environment to maintain stable, constant conditions despite external changes.

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the need for energy input, including processes like diffusion and osmosis.

Front

What is Active Transport?

Back

The movement of substances across a cell membrane against their concentration gradient, requiring energy, often in the form of ATP.

Front

Define Diffusion.

Back

The process by which molecules spread from areas of high concentration to areas of low concentration until equilibrium is reached.

Front

What is Osmosis?

Back

The diffusion of water through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What happens to an animal cell in a hypertonic solution?

Back

The cell will shrink as water moves out of the cell to the area of higher solute concentration.

Front

What role do buffers play in homeostasis?

Back

Buffers help maintain a stable pH in the body by neutralizing excess acids or bases.

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing cells to lose water.

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to another solution, causing cells to gain water.

Front

What is isotonic solution?

Back

A solution that has the same concentration of solutes as another solution, resulting in no net movement of water.
