Question

match the term with its correct description: a. energy b. facilitated diffusion c. endocytosis d. passive transport e. active transport f. exocytosis g. carrier protein h. channel protein transport protein that provides a tube - like opening in the plasma membrane through which particles can diffuse is used during active transport but not passive transport process by which a cell takes in material by forming a vacuole around it particle movement from an area of higher concentration to an area of lower concentration process by which a cell expels wastes from a vacuole a form of passive transport that uses transport proteins particle movement from an area of lower concentration to an area of higher concentration transport protein that changes shape when a particle binds with it

Explanation:

1. "Transport protein that provides a tube - like opening in the plasma membrane": Channel proteins are integral membrane proteins that form channels or pores in the plasma membrane, allowing specific substances to pass through. So it matches h. channel protein.
2. "Process by which a cell expels wastes from a vacuole": Exocytosis is the process where a cell releases substances from a vacuole or vesicle to the extracellular environment. So it matches f. exocytosis.
3. "Particle movement from an area of higher concentration to an area of lower concentration": This is the definition of diffusion. In the context of cell transport, when it occurs without the help of transport proteins for small non - polar molecules, it is simple diffusion. But the general concept here matches passive transport where substances move along the concentration gradient. So it matches d. passive transport.
4. "A form of passive transport that uses transport proteins": Facilitated diffusion is a type of passive transport where transport proteins (either carrier proteins or channel proteins) are used to move substances across the membrane down their concentration gradient. So it matches b. facilitated diffusion.
5. "Particle movement from an area of lower concentration to an area of higher concentration": Active transport is the process by which particles are moved against the concentration gradient (from low to high concentration) and requires energy input. So it matches e. active transport.
6. "Process by which a cell takes in material by forming a vacuole around it": Endocytosis is the process where a cell engulfs materials by forming a vesicle or vacuole around the material. So it matches c. endocytosis.
7. "Transport protein that changes shape when a particle binds with it": Carrier proteins bind to specific substances and change their shape to transport the substances across the membrane. So it matches g. carrier protein.
8. "Is used during active transport but not passive transport": Active transport requires energy (usually in the form of ATP) to move substances against the concentration gradient, while passive transport does not require energy as substances move along the concentration gradient. So it matches a. energy.
