Does active transport generate or require ATP?

Question

I'm studying for my next Biology exam and I came across active transport. It doesn't say if it uses ATP or if it generates it, but I know it's on the exam and I can't seem to find the answer. Please help and don't lecture on how I should do this on my own. My test is tomorrow and my professor is sick with the flu so my entire class is kind of S.O.L.

Answer 1

It requires ATP. But there are different kinds of active transport according to the type of energy they use. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed "primary active transport". "Secondary active transport" involves the use of an electrochemical gradient.

Answer 2

Only active transport requires ATP because it's pushing the substance against its concentration gradient.

Answer 3

Active transport requires ATP because you are carrying something against their concentration gradient. All other kinds of transport don't require ATP because they either diffuse or carry materials with its concentration gradient.

Good luck on the exam!!

Answer 4

Keena Transport

Answer 5

Active transport requires ATP.

ATP is efficient in cells, and it takes energy to get ATP. So think... they can't "generate" without having ATP first.





Think "active" meaning lots of energy required!!
