Active Transport

ANSWER:  Requires the input of energy to move molecules from a low concentration to a high concentration

Bulk Transport

ANSWER:  The movement of relatively large quanities of material into or out of a cell at one time (does not use energy)

Carrier Transport

ANSWER:  The use of proteins in a cell membrane to move molecule from a low concentration on one side to a high concentration on the other.

Endocytosis

ANSWER:  The movement of relatively large quantities of material into a cell at one time.

Exocytosis

ANSWER:  The movement of relatively large quantities of material out of a cell at one time.

Diffusion

ANSWER:  The movement of molecules from a high concentration to a low concentration, without the input of energy

Osmosis

ANSWER:  The movement of water from a high concentration to a low concentration, across a semi-permeable membrane without the input of energy.

Scenario: Osmosis

ANSWER:  Scenario: Salt is poured onto a leech causing it to release its bite from the victim.

Scenario: Bulk Transport

ANSWER:  Scenario: Cell in the human body take cholesterol particles in by endocytosis.

Scenario: Carrier Transport

ANSWER:  Scenario: Cells in the human body have proteins that work to maintain negatively charged particles inside of the cell while keeping positively charged particles outside of the cell. This goes against concentration gradient.

Scenario: Diffusion

ANSWER:  Scenario: Ink that was released into the water by a squid moments later became unnoticeable.

Permeable

ANSWER:  ablity of particle to pass through a membrane

Hypotonic

ANSWER:  The concentration of solutes in the solution is lower than inside the cell.

Hypertonic

ANSWER:  The concentration of solutes in the solution is higher than inside the cell.

Isotonic

ANSWER:  The concentration of solutes inside the cell is the same as outside the cell.
