Front

Equilibrium

Back

A state where the concentrations of all reactants and products remain constant over time.

Front

Exocytosis

Back

The process by which a cell releases large amounts of material.

Front

Hypertonic

Back

A solution with a higher concentration of solutes compared to another solution.

Front

Passive transport

Back

The movement of substances across a cell membrane without the use of energy by the cell.

Front

Permeability

Back

The property of a membrane that allows substances to pass through it.

Front

Concentration gradient.

Back

The concentration gradient is the difference in the concentration of a substance between two areas. Substances will move from high to low concentration

Front

Types of transport that do not require energy.

Back

Passive transport (examples: Diffusion, osmosis, and facilitated diffusion)

Front

Impact of an isotonic environment on an animal cell.

Back

In an isotonic environment, an animal cell maintains its normal shape as water moves in and out at equal rates.

Front

Assumption about cell permeability in the egg lab experiment.

Back

The egg with the shell was impermeable to movement. The egg with no shell had a membrane that was semipermeable.
