Cell Membrane and Transport

Front

What is the primary function of the cell membrane?

Back

To regulate what enters and leaves the cell.

Front

Define exocytosis.

Back

The process of releasing large particles, often waste materials, from the inside of the cell to the outside.

Front

What characterizes an isotonic solution?

Back

An isotonic solution has an equal concentration of solute compared to the inside of the cell.

Front

What is passive transport?

Back

The type of cellular transport that requires no energy.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and may shrink.

Front

What is the difference between active and passive transport?

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the role of transport proteins in the cell membrane?

Back

Transport proteins facilitate the movement of substances across the cell membrane.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solute compared to the inside of the cell.

Front

How does a cell respond to a hypotonic solution?

Back

The cell will gain water and may swell or burst.
