N5S3 - Active Transport - 1.5

Question 1

Define the term “Active Transport”

Answer 1

Active transport is a process that requires energy to move molecules and ions against the concentration gradient

Question 2

Define the term “Passive Transport”

Answer 2

Passive transport is a process that does not require energy to move molecules and ions down the concentration gradient

Question 3

What is active transport dependent on?

Answer 3

Energy from ATP

Question 4

Explain the effect the rate of respiration has on active transport

Answer 4

Because active transport is dependent on ATP, the rate of respiration will affect the rate of active transport e.g. temperature and oxygen avaliability.

Question 5

Identify what part of the cell membrane carries out active transport

Answer 5

It is carried out by proteins in the cell membrane called protein pumps

Question 6

Give an example of what a cell might use active transport for

Answer 6

A cell may use active transport to stop a harmful substance that is at a high concentration outside from building up inside the cell.

Question 7

Describe how the code to make the protein insulin would differ from making the protein amylase

Answer 7

Diiferent proteins have a different order of bases
