During active transport, molecules are moved from a region of ____ concentration to ____ concentration
|
|
high, low
|

|
low, high
|
Explanation:
Detailed explanation-1: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
Detailed explanation-2: -There are two main modes of transport of molecules across any biological membrane. These are passive and active transport. Passive transport, most commonly by diffusion, occurs along a concentration gradient from high to low concentration.
Detailed explanation-3: -The movement of water molecule from a region of higher concentration to a region of its lower concentration through a semi permeable membrane is called Osmosis.
