Question

How are Active and Passive Transport similar? How are they different?

Answer 1

Similarities:
1) Both are biological processes that move oxygen, water and nutrients into cells and remove waste products.

Difference:
Active Transport - requires chemical energy because the process of transport is the movement of biochemicals from areas of lower concentration to higher concentration.

Passive Transport - does not require energy because the process of transport is the movement of biochemicals from areas of higher concentration to lower concentration.

Types of transport:
Active Transport - endocytosis, cell membrane/sodium-potassium pump and exoctyosis

Passive Transport - diffusion, facilitated diffusion, and osmosis.

Types of particles transported:
Active Transport - proteins, ions, large cells, complex sugars

Passive Transport - anything soluble in lipids, small monosaccharides, water, oxygen, carbon dioxide, sex hormone, etc.

Answer 2

Sample Response:

Both passive and active transport move substances into and out of the cell across the cell membrane. However, passive transport does not require the use of energy because molecules move from an area of high concentration to an area of low concentration. Active transport does require the use of energy because molecules move from an area of low concentration to an area of high concentration.
