Cellular Transport

Front

What is the structure of the cell membrane?

Back

The cell membrane is flexible and fluid, not solid and rigid.

Front

What process engulfs large molecules and moves them inside the cell using energy?

Back

Endocytosis.

Front

What is passive transport?

Back

Passive transport is the movement of particles from high concentrations to low concentrations without the use of energy.

Front

What does isotonic mean in terms of solute concentration?

Back

Isotonic means equal percentage of solutes inside and outside the cell, resulting in no net movement of water.

Front

What happens to a cell in an isotonic solution?

Back

The cell stays the same size.

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.

Front

What is exocytosis?

Back

Exocytosis is the process of moving large molecules out of the cell using energy.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the cell membrane.

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 a hypertonic solution?

Back

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