Question

Energy dependent absorption of water against osmotic gradient is

• A. Active absorption
• B. Passive absorption
• C. Imbibition
• D. Bulk absorption

Answer 1

The correct option is A Active absorption

Active absorption requires the input of energy, which is obtained from cellular respiration. The energy input is required because active absorption occurs against the concentration gradient of molecules being transported.

Passive transport occurs along the concentration gradient and does not require the input of energy.
