Active Transport

Question 1

What proteins does active transport use?

Answer 1

Carrier proteins spanning the cell membrane

Question 2

Why does that molecule that is being actively transported bind to?

Answer 2

Specific binding site on the carrier protein

Question 3

Step 3 of active transport- ATP bind?

Answer 3

ATP binds to the carrier protein from the inside of the cell and it is hydrolysed into ADP and Pi and releases energy

Question 4

4th step of active transport? (Phosphate group being attached)

Answer 4

The carrier protein changes shape and releases the molecule to the other side

Question 5

5th step of active transport? (Phosphate ion being released)

Answer 5

Phosphate ion is then released and the protein returns to its original shape
