Step 1I'll solve this problem step by step, focusing on the concept of concentration gradient and active transport.
Step 2: Understanding Concentration Gradient
A concentration gradient represents the difference in the concentration of a substance between two areas. Molecules naturally tend to move from an area of high concentration to an area of low concentration (passive diffusion).
Final Answer
Moving a molecule against the concentration gradient means transporting it from a low concentration area to a high concentration area, which requires energy input and goes against the natural diffusion process.
