Cell Transport

Front

What is the process called when particles move from an area of higher concentration to an area of lower concentration without the use of energy?

Back

Passive transport

Front

What type of passive transport involves the use of transport proteins to move substances like glucose across the cell membrane?

Back

Facilitated diffusion

Front

Can you give an example of facilitated diffusion?

Back

Glucose transport

Front

What structure in the cell is responsible for regulating the entry and exit of substances?

Back

Cell Membrane

Front

What happens to a cell placed in a hypotonic solution?

Back

The cell expands and may burst (lyse).

Front

What is the term for the movement of water across a selectively permeable membrane?

Back

Osmosis

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is a hypertonic solution?

Back

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

Front

What is the role of transport proteins in facilitated diffusion?

Back

Transport proteins help move specific molecules across the cell membrane without using energy.

Front

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

Back

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