Jacob bio quiz 8.17 Cell Transport

Vocabulary-style flashcards based on lecture notes covering passive and active cell transport mechanisms, including endocytosis, exocytosis, and tonicity states.

CELL TRANSPORT

Movement of materials in and out of a cell

PASSIVE TRANSPORT

A form of transport where no energy/ATP is required

SIMPLE DIFFUSION

Molecules move from high to low concentration

FACILITATED DIFFUSION

A form of passive transport that uses membrane proteins or protein channels to move molecules from high to low

OSMOSIS

The movement (diffusion) of water through a cell membrane

ACTIVE TRANSPORT

Uses energy (ATP) to move solutes against their gradients from low to high concentration

ENDOCYTOSIS

The process in which materials are taken in by a cell

PINOCYTOSIS

Also known as cell drinking; the movement of liquids and dissolved substances into a cell

PHAGOCYTOSIS

Also known as cell eating; the movement of large particles, such as food or bacteria, into a cell

EXOCYTOSIS

The process in which materials are released from a cell; a form of active transport in which a cell transports molecules out of the cell

Isotonic

A state at equilibrium with $50\% \text{ water/ } 50\% \text{ solute}$; same water inside and out

Hypertonic

A state with more water inside than out, causing the cell to shrink

Hypotonic

A state with more water outside than inside
