What are the differences between active transport and simple diffusion along and against concentration gradients?
Understand the Problem
The question is asking for clarification or information about the processes of active transport and diffusion in biological systems, specifically how they operate along or against concentration gradients.
Answer
Simple diffusion along the concentration gradient, i.e., from higher to lower concentration.
The final answer is simple diffusion along the concentration gradient, i.e., from higher concentration to the lower.
Answer for screen readers
The final answer is simple diffusion along the concentration gradient, i.e., from higher concentration to the lower.
More Information
Simple diffusion is a passive process that moves molecules from an area of high concentration to low concentration, following the natural tendency to equalize concentrations without using energy.
Tips
Do not confuse simple diffusion with active transport, which requires energy and moves substances against their concentration gradient.
