Answer:
Active transport is requires energy because it is not a passive process.
Explanation:
The molecule has to go against the concentration gradient.
Answer: Why is energy needed for active transport? Because active transport is required to have energy, but it is not a supine process. The molecule basically has to go AGAINST the concentration slope. For this reason, it requires energy to be carried by the carrier proteins.
Hope this helps yaa!! :-)
