Question

State whether the following statements are true or false.
The movement of ions or molecules against a concentration gradient with the utilisation of energy is known as active transport.

• A. True
• B. False

Answer 1

The correct option is A True

The movement of ions or molecules against a concentration gradient (from lower to higher concentration) across a cell membrane with the utilization of energy is known as active transport. Active transport needs cellular energy which is given by ATP hydrolysis.

So, the correct option is 'True'.
