Cell Transport

Front

What is osmosis?

Back

Osmosis is the movement of water and other solvents across a membrane.

Front

What is active transport?

Back

Active transport is the process that requires energy to move substances up the concentration gradient.

Front

What type of solution is used in IVs for normal cells?

Back

Isotonic solution is used in IVs for normal cells.

Front

What is diffusion?

Back

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

Front

What happens if there is too much salt in your cells?

Back

If there is too much salt in your cells, you need more water.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of 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 water to enter the cell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to leave the cell.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance across a space.

Front

What role do cell membranes play in transport?

Back

Cell membranes control the movement of substances in and out of the cell, maintaining homeostasis.
