Cellular Transport Vocab Quizs

Homeostasis

• The process of maintaining a stable internal environment within an organism.

• The ability to adapt to external changes in the environment.

• The mechanism of cellular respiration in organisms.

• The method of reproduction in living organisms.

Protein pump/channel

• Proteins that assist in moving substances across the membrane, often against a concentration gradient.

• Proteins that only allow passive transport of substances across the membrane.

• Proteins that are involved in the synthesis of lipids in the cell membrane.

• Proteins that serve as receptors for signaling molecules on the cell surface.

Potassium pump ATP

• A type of passive transport that does not require energy.

• A type of active transport that uses ATP to move potassium ions into the cell and sodium ions out of the cell.

• A mechanism that only moves sodium ions out of the cell.

• A process that occurs only in plant cells.

Exocytosis

• The process by which cells expel materials in vesicles that fuse with the plasma membrane.

• The process by which cells take in materials through vesicles.

• The process of cell division that results in two identical daughter cells.

• The process by which cells convert glucose into energy.

Endocytosis

• The process by which cells engulf substances into a pouch which then becomes a vesicle.

• The process by which cells expel waste materials from the cell.

• The process of cell division resulting in two daughter cells.

• The process by which cells take in nutrients through active transport.

Diffusion

• The movement of particles from an area of higher concentration to an area of lower concentration.

• The process of particles moving from an area of lower concentration to an area of higher concentration.

• The random movement of particles in a vacuum without any concentration gradient.

• The process of particles being absorbed by a solid surface.

Simple diffusion

• The movement of molecules from an area of lower concentration to an area of higher concentration using energy.

• The movement of molecules from an area of higher concentration to an area of lower concentration without the use of energy.

• The movement of molecules against their concentration gradient with the use of energy.

• The random movement of molecules in a solution without any concentration gradient.

Cell membrane

• A rigid barrier that protects the cell from external damage.

• The semipermeable membrane surrounding the cytoplasm of a cell, controlling the movement of substances in and out.

• A structure that provides energy to the cell through respiration.

• A component that stores genetic information within the cell.

High to low concentration gradient

• Active transport

• Facilitated diffusion

• Passive transport

• Endocytosis

Osmosis

• The movement of solutes from an area of high concentration to an area of low concentration.

• The diffusion of water across a selectively permeable membrane.

• The process of active transport of ions across a membrane.

• The absorption of nutrients through the cell wall.
