Biology Vocab #5

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

• Active transport
• Passive transport
• Facilitated diffusion
• Endocytosis

The movement of particles from regions of higher destiny to regions of lower density. Moves small solutes

• Osmosis
• Evaporation
• Diffusion
• Convection

A difference in the concentration of a substance across a distance.

• Concentration level
• Diffusion rate
• Substance density
• Concentration gradient

A solution whose solute concentration is HIGHER than the solute concentration inside a cell. Causes a cell to shrink.

• isotonic solution
• hypotonic solution
• saturated solution
• hypertonic solution

A solution whose solute concentration is LOWER than the solute concentration inside a cell. Causes the cell to swell

• Saturated solution
• Isotonic solution
• Hypertonic solution
• Hypotonic solution

Describes a solution whose solute concentration is EQUAL to the solute concentration inside a cell.

• Hypertonic solution
• Saturated solution
• Isotonic solution
• Hypotonic solution

The bursting of a cell.

• Apoptosis
• Endocytosis
• Cytolysis

• Exocytosis

The transportation of substances through a cell membrane along a concentration gradient with the aid of carrier proteins. Passive and moves large particles

• Facilitated Diffusion
• Active Transport
• Osmosis
• Diffusion

A protein that transport substances across a cell membrane.

• Carrier protein

• Enzyme protein
• Structural protein
• Receptor protein

A complex of protein molecules in a cell membrane that forms a pore through which ions can pass.

• Ion channel
• Transporter protein
• Receptor protein
• Ion pump
