Passive & active transport

Question 1

Passive transport:

Answer 1

Moves substances from an area of higher concentration to an area of lower concentration (down the concentration gradient)

Question 2

Passive transport energy wise:

Answer 2

Does not require energy

Question 3

Three types of passive transport:

Answer 3

1. Diffusion
2. Osmosis
3. Facilitated diffusion

Question 4

Active transport:

Answer 4

Moves substances from an area of lower concentration to an area of higher concentration (against the concentration gradient).

Question 5

Active transport energy wise:

Answer 5

Requires energy (usually in the form of ATP)
