Macon: Homeostasis, Feedback, & Cell Transport

Front

What is Homeostasis?

Back

Homeostasis is the state of stability or equilibrium in an organism, where internal conditions remain constant despite external changes.

Front

Define Cell Transport.

Back

Cell transport refers to the movement of materials in and out of cells, which is essential for maintaining homeostasis.

Front

What is Diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is Active Transport?

Back

Active transport is the process that requires energy to move materials against their concentration gradient.

Front

What does Hypotonic mean?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing cells to swell as water enters.

Front

What does Hypertonic mean?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, causing cells to shrink as water exits.

Front

What is Isotonic?

Back

An isotonic solution has an equal concentration of solutes compared to another solution, resulting in no net movement of water.

Front

Explain Osmosis.

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance between two areas, which drives diffusion and transport processes.

Front

What is Facilitated Diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.
