Cell Transport

Front

What happens to a cell in a hypertonic solution?

Back

Water moves from the inside of the cell to the solution, causing the cell to shrink.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of molecules diffusing with the concentration gradient through a protein channel.

Front

What types of transport use energy?

Back

Endocytosis and exocytosis both use energy.

Front

What happens to a red blood cell in a salt solution?

Back

The red blood cell will shrink.

Front

In a beaker with 96% water and 4% salt, where will water move if dialysis tubing with 88% water and 12% salt is added?

Back

Water molecules will move from the beaker to inside the tubing.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of protein channels in cell transport?

Back

Protein channels facilitate the movement of specific molecules across the cell membrane.
