Cell Transport

Front

What is Passive Transport?

Back

Passive Transport is the movement of solutes across a cell membrane without the use of energy, following the concentration gradient.

Front

What is Active Transport?

Back

Active Transport is the movement of solutes against the concentration gradient, requiring energy to move materials across the cell membrane.

Front

What role does the cell membrane play in homeostasis?

Back

The cell membrane controls what substances may enter or leave the cell, helping to maintain homeostasis.

Front

What is the primary requirement for Active Transport?

Back

Active Transport requires energy to move materials across the cell membrane.

Front

In which type of solution does water enter the cells?

Back

Water enters the cells in a Hypotonic Solution.

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 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

Define Osmosis.

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes from high to low concentration, while osmosis specifically refers to the movement of water.

Front

What is the function of transport proteins in Active Transport?

Back

Transport proteins help move substances across the cell membrane against their concentration gradient, requiring energy.
