Explain concentration gradient.
Understand the Problem
The question is asking for an explanation of the concept of concentration gradient, which refers to the difference in concentration of a substance between two areas. This typically involves discussing how substances move from an area of higher concentration to an area of lower concentration.
Answer
Concentration gradient: particles move from high to low concentration areas.
A concentration gradient is the process where particles move through a solution or gas from a region of higher concentration to one of lower concentration, often separated by a membrane.
Answer for screen readers
A concentration gradient is the process where particles move through a solution or gas from a region of higher concentration to one of lower concentration, often separated by a membrane.
More Information
Concentration gradients are vital in many biological processes like nutrient absorption and nerve signal transmission.
Tips
A common mistake is confusing concentration gradient with equilibrium, where no net movement occurs as the concentrations are equal.
