Open in App
Solution
The correct option is C passive transport
When molecules are transported along the concentration gradient i.e., from higher to lower concentration, there is no utilization of energy. This is called passive transport.
Active transport involves the expenditure of energy in the form of ATP (adenosine triphosphate) as the movement of molecules is against the concentration gradient i.e., from low to high concentration.
