Question

correctly match the terms and definitions from this chapter below.
membrane transport through proteins that speeds the passive movement of molecules across the plasma membrane choose
facilitated diffusion protein that provides corridors that allow a specific molecule or ion to cross the membrane choose
facilitated diffusion protein that undergoes a subtle change in shape that translocates the solute - binding site across the membrane choose
membrane transport that moves substances against their concentration gradients choose
transport that occurs when active transport of a solute indirectly drives transport of other solutes choose
transport vesicles migrate to the membrane, fuse with it, and release their contents choose
the cell takes in macromolecules by forming vesicles from the plasma membrane choose

Explanation:

To solve this, we match each term with its correct definition based on concepts in cell membrane transport (from Biology, a subfield of Natural Science):

1. Membrane transport through proteins that speeds the passive movement of molecules across the plasma membrane → Facilitated Diffusion (passive transport aided by proteins).
2. Facilitated diffusion protein that provides corridors that allow a specific molecule or ion to cross the membrane → Channel Protein (forms channels for specific substances).
3. Facilitated diffusion protein that undergoes a subtle change in shape that translocates the solute - binding site across the membrane → Carrier Protein (changes shape to transport solutes).
4. Membrane transport that moves substances against their concentration gradients → Active Transport (requires energy, moves against gradient).
5. Transport that occurs when active transport of a solute indirectly drives transport of other solutes → Cotransport (one solute’s active transport drives another’s movement).
6. Transport vesicles migrate to the membrane, fuse with it, and release their contents → Exocytosis (vesicles release substances outside the cell).
7. The cell takes in macromolecules by forming vesicles from the plasma membrane → Endocytosis (cell engulfs macromolecules via vesicle formation).

Answer:

s (matching each term to definition):

1. Facilitated Diffusion
2. Channel Protein
3. Carrier Protein
4. Active Transport
5. Cotransport
6. Exocytosis
7. Endocytosis
