Question

Why is energy required for active transport?

Answer 1

Active transport:

1. Active transport is the process of the transfer of molecules across a semi-permeable membrane.
2. The molecules move against the concentration gradient.
3. The movement of molecules occurs from a region of low concentration to a region of high concentration.
4. This is why it is an energy-intensive process, as energy in the form of ATP is required to transfer molecules against the concentration gradient.
