Cell Transport Introduction

The liquid that substances are dissolved in.

In biology, this is usually water, which can be both

inside and outside of a cell.

Active Transport of molecules (often waste products)

out of a cell using ATP.

Active Transport of molecules (often waste products)

out of a cell using ATP.

• Exocytosis

• Endocytosis

• Passive Transport

• Facilitated Diffusion

Diffusion (passive transport) of molecules using

protein channels (tunnels) through the cell membrane without using energy.

• Active Transport

• Endocytosis

• Exocytosis

• Facilitated Diffusion

Steady state: The maintenance of a balanced, safe, internal environment inside of a cell, regulated by the cell membrane.

• Cellular Metabolism

• Homeostasis

• Active Transport

• Facilitate Diffusion

Higher concentration of solute (usually salt or sugar) outside a cell than inside a cell so that water moves out of the cell causing it to implode or be crushed.

• Hypertonic Solution

• Homeostatic Solution

• Hypotonic Solution

• Endocytosis
