Cell Transport

Front

What is osmosis?

Back

The diffusion of water.

Front

True or False: Active transport moves molecules down their concentration gradients.

Back

False.

Front

Which solute has the higher concentration of water?

Back

Solution 1.

Front

What is this process called? (Endocytosis or Exocytosis)

Back

Exocytosis.

Front

What does it mean for a membrane to be partially permeable?

Back

It allows some molecules to pass through it.

Front

Define diffusion.

Back

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

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is the role of the cell membrane in transport?

Back

It regulates what enters and exits the cell.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a membrane via specific transmembrane proteins.

Front

What is endocytosis?

Back

The process by which cells internalize substances from their external environment.
