low; high
Explanation
## Step 1: Active transport is a biological process in cells, where substances are moved across cell membranes. This process is against the concentration gradient, which means substances are moved from an area of lower concentration to an area of higher concentration. ## Step 2:This process requires energy, typically in the form of ATP (Adenosine Triphosphate). This is what differentiates it from passive transport, where substances move from an area of higher concentration to an area of lower concentration, without the use of cellular energy.
