Question 22

Move against the concentration.

Answer 22

Primary Active Transport

Question 23

Low concentration to high concentration
Require energy (ATP)

Answer 23

Primary Active Transport

Question 24

Primary Active Transport – Ion pump

1. ATP will attach and stimulate/ change the shape of the ion pump
2. ATP will allow 3 N__ion into the pump
3. ATP will change into _____ and P
4. ADP will be released back into the cytoplasm as P will remain attach to the pump

Answer 24

ATP will attach and stimulate/ change the shape of the ion pump

ATP will allow 3 Na ion into the pump

ATP will change into ADP and P

ADP will be released back into the cytoplasm as P will remain attach to the pump
