cell transport

Front

What is the process by which water moves across a semipermeable membrane?

Back

Osmosis

Front

What happens to a cell when it is placed in a hypotonic solution?

Back

The cell swells and may burst due to water influx.

Front

What is a hypertonic solution?

Back

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

Front

What is the effect of placing a cell in isotonic solution?

Back

There is no net movement of water; the cell remains the same size.

Front

What does it mean for a solution to be isotonic?

Back

It has the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What is diffusion?

Back

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

Front

What is facilitated diffusion?

Back

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

Front

What role do transport proteins play in cell transport?

Back

They help move substances across the cell membrane that cannot directly diffuse through the lipid bilayer.

Front

What is the significance of the Benedict's test in relation to glucose?

Back

It indicates the presence of reducing sugars, such as glucose, in a solution.

Front

What is the primary function of the cell membrane?

Back

To regulate what enters and exits the cell, maintaining homeostasis.
