The cell is taking in substances through membrane proteins without any energy expenditure of its own. The substances naturally follow their concentration gradient. However, they must go through the protein channels because they are too large to squeeze through the cell membrane. This process is called:

_____

Fill in the blank with the name of the process described.

Facilitated diffusion . because the protein channels must help the substance get into the cell based on fitting. It's important to regulating what comes in and goes out.

The right answer is facilitated diffusion.
Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.

The correct term for the process described is facilitated diffusion, a passive transport mechanism that uses protein channels to help large or polar substances move across the cell membrane down their concentration gradient without energy expenditure. This method is crucial for transporting essential molecules like glucose into the cell. Essentially, facilitated diffusion is vital for regulating what enters and exits the cell, supporting its overall function.
