Concept 2 Vocab: Cell Transport

Front

Controls movement in/out of cell:

Back

Cell Membrane

Front

Requires no extra energy from the cell

Back

Passive Transport

Front

Molecules move from high to low concentration

Back

Passive Transport

Front

Requires extra energy to move materials in/out of the cell

Back

Active Transport

Front

Moves materials against concentration gradient

Back

Active Transport

Front

Maintains homeostasis in response to stimuli

Back

Feedback mechanisms

Front

Type of feedback mechanism that intensifies response, e.g., fruit ripening.

Back

Positive Feedback Loop

Front

Type of feedback mechanism where output causes a counter response to return to a set point (e.g., blood sugar regulation).

Back

Negative Feedback Loop

Front

What gets dissolved? Example: Lemonade Powder

Back

Solute

Front

What dissolves? Example: water

Back

Solvent
