Cell Biology Flashcards

Front

Active Transport

Back

Process needing ATP energy for the movement of particles across a cell membrane

Front

Cell Membrane

Back

A thin, flexible, semipermeable barrier around the cell which controls what enters and leaves the cell.

Front

(simple) Diffusion

Back

The process when molecules tend to move from an area of high concentration to an area of low concentration.

Front

ATP energy

Back

Energy needed by the cell to do work

Front

Hypertonic

Back

A solution that causes a cell to shrink because of the high concentration of solute in the solution surrounding the cell.

Front

Hypotonic

Back

A solution that causes a cell to swell (get bigger) because of osmosis.

Front

Osmosis

Back

This is a process in which water moves through a membrane, from an area of high concentration to an area of lower concentration.

Front

Isotonic

Back

When the concentration of solute and solvent are equal on both sides of the membrane.

Front

Passive Transport

Back

A non-energy requiring process that moves from an area of high concentration to an area of low concentration.

Front

Semipermeable

Back

Only certain molecules can pass through
